Q24 of 107 Page 12

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


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
