# 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) isA. 50√3B. 150√3C. 150√2D. 75

Here AB is the tower of 150m which forms the angel of depression = 30° from the top

Hence the angle of elevation from the car is 90° - 30° = 60°

In Δ ABC

tan 60° =

BC =

BC = 50 √3 m
