Question

Find the angle of depression from the top of 15 m high tower of an object lying at a
point 15m away from the base of the tower.​

Answer 1

Answer:

                Answer is 45°

Step-by-step explanation:

Refer the attached figure .

Height of tower = AB = 15 m

A point is 15 m away from the base i.e. BC = 15 m

Perpendicular = 15 m

Base = 15 m

We are supposed to find ∠ACB

So, we will use trigonometric ratio:

Thus the angle of elevation of the top of 15m high tower at a point 15m away from the base of tower is 45°
