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.
