The angle of depression of a car parked on the road from the top of a 150 m high tower is 30°. The distance of the car from the tower (in metres) is
Given a high tower whose height, AC = 150m
Angle of depression, ∠DCB = 30°

We know that alternate angles are equal.
⇒ ∠DCB = ∠ABC
Let distance of the car from tower, AB = x m
In ΔABC, tan 30° ![]()
![]()
⇒ x = 150√3
∴ The distance of car from the tower is 150√3 m.
