A tower stands on the top of a hill. The angle of elevation of the top of the tower from a point on the ground is 60°. If the height of the tower is 20 m and the height of the hill is 10 m, find the distance of the point from the foot of the hill.
Q1. A tower stands on the top of a hill. The angle of elevation of the top of the tower from a point on the ground is 60°. If the height of the tower is 20 m and the height of the hill is 10 m, find the distance of the point from the foot of the hill.
Answer: 30 / √3 m
Explanation: tan 60° = (20 + 10) / distance. So, distance = 30 / √3 m.
