The angle of depression of a point on the ground from the top of a tower is 30°. If the height of the tower is 20 m, find the distance of the point from the tower.
Q1. The angle of depression of a point on the ground from the top of a tower is 30°. If the height of the tower is 20 m, find the distance of the point from the tower.
Answer: 20 √3 m
Explanation: tan 30° = 20 / distance. So, distance = 20 / tan 30° = 20 √3 m.
