A tower stands on a horizontal plane. The angle of elevation of its top from a point on the ground is 30°. At a point 20 m nearer to the tower, the angle becomes 60°. Find the height of the tower.
Q1. A tower stands on a horizontal plane. The angle of elevation of its top from a point on the ground is 30°. At a point 20 m nearer to the tower, the angle becomes 60°. Find the height of the tower.
Answer: 17.32 m
Explanation: Using tan 30° and tan 60°, we form equations to solve for the height.
