Q. 22

# The angle of depression of a car, standing on the ground, from the top of a 75 m tower, is 30°. The distance of the car from the base of the tower (in metres) isA. 25√3B. 50√3C. 75√3D. 150

Here AB is the tower of height 75m forming angle of depression = 30°

Angle of elevation is 90° - 30° = 60°

tan 60° =

√3 =
