From the top of a tower 100 m high, the angle of depression of a point on the ground is 30°. Find the distance of the point from the foot of the tower.
Q1. From the top of a tower 100 m high, the angle of depression of a point on the ground is 30°. Find the distance of the point from the foot of the tower.
Answer: 173.2 m
Explanation: tan 30° = 100 / distance, so distance = 100√3 = 173.2 m.
