Angle of Depression Definition, Formulas, Examples | How to Find Angle of Depression?

Angle of Depression

The angle of depression is created when the observer is higher than the object he is looking at. If a person looks at an object that is located at a distance lower than the person, the angle is formed below the horizontal line drawn with the level of the eye of the person and line joining object with the person’s eye. This angle is calculated by using the concept of trigonometry. Get the definition, formulas, and example questions with answers in the below sections.

Angle of Depression – Definition

The angle of depression is the angle formed between the horizontal line and the observation of the object from the horizontal line. This angle of depression is used to find the distance between the two objects when the angles, object’s distance from the ground are known parameters. It is also defined as the angle that is constructed with the horizontal line if the line of sight is downward from the horizontal line.

Angle of Depression 1

If the object observed by the observer is below the level of the observer, then the angle created between the horizontal line and the observer’s line of sight is called the angle of depression. In the above figure, θ is the angle of depression.

Angle of Depression Formulas

With the angle of elevation, if you know two sides of the right triangle are known, then the formula of the angle of depression is

tan θ = \(\frac { Opposite Side }{ Adjacent Side } \)

θ = tan-1 (\(\frac { Opposite Side }{ Adjacent Side } \))

Also, check

Angle of Elevation and Angle of Depression

The angle of elevation and angle of depression are opposite to each other. The elevation angle is formed when it is between the line of sight and the horizontal line. And if the line of sight is above the horizontal line, then the angle is called the angle of elevation. In the angle of depression, the line of sight is downwards to the horizontal line.

Angle of Depression 2

∠ABO = ∠O = θ

Angle of Depression Problems

Example 1:

The angles of elevation and depression of the top and bottom of a lamp post from the top of a 66 m high apartment are 60° and 30° respectively. Find (i) The height of the lamp post. (ii) The difference between the height of the lamp post and the apartment. (iii) The distance between the lamp post and the apartment.

Solution:

Angle of Depression 3

Triangle AED forms a right triangle

So, tan 60° = \(\frac { ED }{ AD } \)

√3 = \(\frac { ED }{ AD } \)

AD = \(\frac { ED }{ √3 } \) —- (i)

In trinagle ABC,

tan 30° = \(\frac { AB }{ BC } \)

\(\frac { 1 }{ √3 } \) = \(\frac { 66 }{ BC }\)

BC = 66√3 —- (ii)

Equating both equations

\(\frac { ED }{ √3 } \) = 66√3

ED = 66√3 (√3 )

ED = 66(3)

ED = 198

(i) Height of lamp post = ED + DC

= 198 + 66

= 264 m

(ii) The difference between height of the lamp post and the apartment

= 364 – 66

= 198 m

(iii) The distance between the lamp post and the apartment

BC = 66√3

= 66(1.732)

= 114.31 m

Example 2:

An airplane is flying at a height of 2 miles above level ground. The angle of depression from the plane to the foot of the tree is 15°. What is the distance the plane must fly to be directly above the tree?

Solution:

Angle of Depression 4

To find the distance BA use the tangent function

tan 15° = \(\frac { 2 }{ BA } \)

0.26794919243 = \(\frac { 2 }{ BA } \)

BA = \(\frac { 2 }{ 0.26794919243 } \)

BA = 7.464

So, the plane must fly 7.464 ft horizontally to be directly over the tree.

Example 3:

A buoy in the ocean is observed from the top of a 40-meter-high oil rig. The angle of depression from the top of the tower to the buoy is 6°. How far is the buoy from the base of the oil rig?

Solution:

Given that,

The angle of depression from the top of the tower to the buoy = 6°

A buoy in the ocean is observed from the top of a 40-meter-high oil rig.

Tan 6° = \(\frac { 40 }{ h } \)

h = \(\frac { 40 }{ tan 6° } \)

h = \(\frac { 40 }{ 0.105104 } \)

h = 380.6

It is approximately 380.6 m from the buoy to the base of the oil rig.

Example 4:

A lift in a building of height 90 feet with transparent glass walls is descending from the top of the building. At the top of the building, the angle of depression to a fountain in the garden is 60°. Two minutes later, the angle of depression reduces to 30°. If the fountain is 30√3 feet from the entrance of the lift, find the speed of the lift which is descending.

Solution:

Angle of Depression 5

In the diagram above, in the right triangle ABC,

tan 30° = \(\frac { Opposite side }{ adjacent side } \)

\(\frac { 1 }{ √3 } \) = \(\frac { BC }{ 30√3 } \)

1 x 30√3 = √3 x BC

BC = 30

DC = DB – CB

DC = 90 – 30

DC = 60 feet

So, the left has descended 60 ft in 2 minutes.

Speed = \(\frac { Distance }{ Time } \)

Speed = \(\frac { 60 }{ 2 } \)

Speed = 30 ft/min

Let us discuss the definitions of each one of them and the differences between them in the below sections of this page.

What is Line?

A line can be defined as a straight set of points that extend in opposite directions. It is a one-dimensional figure and does not have a thickness, end in both directions.

Line 1

The different types of lines are horizontal lines, vertical lines, parallel lines, and perpendicular lines. The images of these types are provided here for a better understanding of the concept.

Line 2

If a line moves from left to right in a straight direction, it is a horizontal line.

Line 3

If a line moves from top to bottom in a straight direction, then it is called the vertical line.

Line 4

When two or more straight lines do not intersect each other at any point, then those are called parallel lines. The points A, B, C, D are called the points on the lines.

Line 5

If two lines meet at a point at right angles, then they are perpendicular to each other.

Solved Examples on Mass and Weight Unit Conversions

1. Calculate the conversion of 650 g into kilograms.

Solution:

We know 1 Gram = \(\frac { 1 }{ 1000 } \) Kilogram

650 g = \(\frac { 650 }{ 1000 } \) kg

650 g = 0.65 kg

Hence, 650 g converted to kilograms if 0.65 kg.

2. Convert 87 decigram into grams.

Solution:

87 dg = \(\frac { 87 }{ 10 } \) g

= 8.7 g

3. Find the conversion of 6.9 kg into dag.

Solution:

6.9 kg = 6 kg + 900 g

We know, 1 dag = 10 g

So, 6900 g = \(\frac { 6900 }{ 10 } \) dg

= 690 dag

Dividing Fractions Definition, Examples | How to Divide Fractions?

Dividing Fractions

In the earlier grades, you must have learned about the division of natural numbers and whole numbers. Fractions are expressed in ratios where numerator and denominator are integers and not equal to zero. Here, we have mentioned the Division of Fractions by using different methods along with examples. Fractions Division is a bit difficult so we have provided an easy and alternative method to perform Division of Fractions. Rather than doing division, you can perform multiplication as it is quite simple in comparison.

Refer to the procedures on how to divide fractions using different methods. For better understanding, we even provided solved examples for a better understanding of the concept.

What is meant by Dividing Fractions?

Dividing Fractions is simply a multiplication of fractions by reversing one of the two fractions or by writing the reciprocal of one of the fractions. If a fraction is given as a/b, then the reciprocal is b/a and is obtained by interchanging the numerator and denominator with each other.

How to Divide Fractions?

Division of Fractions are classified into three different ways and they are as such

  • Dividing fractions by a fraction
  • Dividing fractions by whole number
  • Dividing fractions by mixed fraction

Continue reading the further modules to learn about all three procedures in a detailed way.

Dividing Fraction by a Fraction

Refer to the Procedure of dividing fractions by converting them into a multiplication of fractions. The procedure is as follows

  • Write the Reciprocal of Second Fraction and then multiply with the first fraction number.
  • Multiply the Numerators and Denominators of both the fractions.
  • Simplify the fraction if possible.

If \(\frac { a }{ b } \), \(\frac { c }{ d } \) are two fractions then

\(\frac { a }{ b } \) ÷ \(\frac { c }{ d } \) = \(\frac { a }{ b } \)*\(\frac { d }{ c } \)

= \(\frac { (a×d) }{ (b×c) } \)

= \(\frac { (ad) }{ (bc) } \)

From the above expressions it is clear that we divided \(\frac { a }{ b } \) with \(\frac { c }{ d } \) and then rewrote the same as multiplication of reciprocal of second term i.e. \(\frac { c }{ d } \). Later multiply both the numerators a,d and denominators b,c.

Dividing Fraction by a Whole Number

Division of Fractions with the Whole Number is quite simple. Go through the procedure below to learn how to divide fractions with a whole number. They are along the lines

Step 1: In the first step, change the whole number to a fraction by placing the denominator value 1.

Step 2: Take the Reciprocal of a Number

Step 3: Multiply the fractional value with the given fraction.

Step 4: Simplify the obtained result if possible.

Example:

Divide 3/10 with 5?

Solution:

Given Whole Number is 5

Convert it to a fraction by placing the numerator value as it is  and the denominator as 1 i.e. \(\frac { 5 }{ 1 } \)

Take the reciprocal of it i.e. \(\frac { 1 }{ 5 } \)

Multiply \(\frac { 3 }{ 10 } \) and \(\frac { 1 }{ 5 } \) i.e. \(\frac { 3 }{ 10 } \) *\(\frac { 1 }{ 5 } \)

= \(\frac { 3 }{ 50 } \)

Dividing Fractions by a Mixed Fraction

Process of Dividing fractions by a mixed fraction is similar to dividing fraction by fraction. The Procedure to follow for fractions by a mixed fraction are given in the below modules. They are as such

Step 1: In the initial stage convert the given mixed fraction to improper fraction

Step 2: After that, take the reciprocal of the given improper fraction

Step 3: Multiply the obtained fraction with the given fraction

Step 4: Simplify the resultant fraction to possible extent.

Example:

Divide \(\frac { 3 }{ 4 } \) and 5 \(\frac { 1 }{ 2 } \)?

Solution:

Given Mixed Fraction is 5 \(\frac { 1 }{ 2 } \)

Convert it to Improper Fraction i.e. \(\frac { 11 }{ 2 } \)

Take the reciprocal of improper fraction \(\frac { 11 }{ 2 } \) i.e. \(\frac { 2 }{ 11 } \)

Multipy \(\frac { 3 }{ 4 } \) and \(\frac { 2 }{ 11 } \) i.e. \(\frac { (3*2) }{ (4*11) } \)

= \(\frac { 6 }{ 44 } \)

Simplifying it further we get \(\frac { 3 }{ 22 } \)

Solved Problems on Mensuration

Here are some questions that help you to understand the concept of Mensuration. Use the Mensuration formulas to solve the problems.

1. Find the Length of the Rectangle whose Perimeter is 24 cm and Width is 3 cm?

Solution:

Given that,
Perimeter = 24 cm
Width = 3 cm
Perimeter of the rectangle = 2(l + w)
24 cm = 2(l + 3 cm)
2l + 6 = 24
2l + 6 = 24
2l = 24 – 6 = 18
2l = 18
l = 9 cm
Thus length of the rectangle = 9 cm

2. Calculate the volume of the Cuboid whole base area is 60 cm² and height is 5 cm.

Solution:

Given,
Base area = 60 cm²
Height = 5 cm
Volume of the Cuboid = base area × height
V = 60 cm² × 5 cm
V = 300 cm³
Thus the volume of the cuboid is 300 cm³.

3. Find the area of the Cube whose side is 10 centimeters.

Solution:

Given, side = 10 cm
Lateral Surface Area = 4a²
LSA = 4 × 10 × 10 = 400 cm²
Total Surface Area = 6a²
= 6 × 10 × 10 = 600 cm²
Volume of the cube = a³
V = 10 × 10 × 10 = 1000 cm³
Therefore the volume of the cube is 1000 cubic centimeters.

4. What is the lateral surface area of the sphere if the radius is 5 cm.

Solution:

Given,
The radius of the sphere = 5 cm
The formula for LSA of sphere = 4Πr²
Π = 3.14 or 22/7
LSA = 4 × 3.14 × 5 cm × 5 cm
LSA = 314 sq. cm
Thus the lateral surface area of the sphere is 314 sq. cm

5. What is the area of the parallelogram if the base is 15 cm and height is 10 cm.

Solution:

Given, Base = 15 cm
Height = 10 cm
