A cable is connected to the top of a building that is 20
20
ft
high. The cable is attached to the ground 35
35
ft
away from the building.

What is the angle of depression from the top of the building to the ground?

Round to the second decimal place.

The angle of depression is 30°

Step-by-step explanation:

The building height= 20ft.

The distance from the building the cable is attached to the ground = 35ft.

Let the angle at the top of the building be 'a'

Refer the diagram.

We can say that,

a° + angle of depression= 90°

Tan a° = opposite side/ adjacent side

Tan a° = 35/20

Tan a° = 7/4

Tan a° = 1.75

Tan 60° = 1.75

Tan a° = tan 60°

a° = 60°

So the angle of depression= 90° - 60°

Angle of depression= 30°
