Question

1. What is the angle of elevation if they are standing at a distance of 42m away from the monument?
​

Answer 1

The Angle of elevation is 45° if they are standing at a distance of 42m away from the 42 m height monument

Given:

• Monument Height = 42 m  ( Missing Info Added)
• Standing at a distance of 42m away from the monument

To Find:

• The angle of elevation

Solution:

• Tan α = Vertical Distance/ Horizontal Distance
• α = angle of elevation

Step 1:

Assume that angle of elevation is α  Hence

Tan α = Vertical Distance/ Horizontal Distance

Step 2:

Substitute Vertical Distance = Height of monument = 42 m and

Horizontal Distance =  standing at a distance  = 42m

Tan α =42/ 42

Tan α =1

Step 3:

Use Tan 45° = 1  Hence

α = 45°

So, The Angle of elevation is 45°

Answer 2

Answer:

45°

Step-by-step explanation:

tan a= 42/42

=1

so tan 45 ° is the answer
