A vertical tower subtends an angle of 60° at a point on the level ground. At a point 20 m vertically above the first point, the angle subtended is 30°. What is the height of the tower?
Q1. A vertical tower subtends an angle of 60° at a point on the level ground. At a point 20 m vertically above the first point, the angle subtended is 30°. What is the height of the tower?
Answer: 30 m
Explanation: Using the tangent function for both angles and the given height, we can form equations to solve for the height of the tower.
