A man observes the angle of elevation of the top of a tower to be 30°. He walks towards it and finds the angle of elevation to be 60° when he is at a distance d from the tower. Find the height of the tower.
Q1. A man observes the angle of elevation of the top of a tower to be 30°. He walks towards it and finds the angle of elevation to be 60° when he is at a distance d from the tower. Find the height of the tower.
Answer: 2d / √3
Explanation: Relating the two positions using tangent, we get height = d√3 / (√3 - 1/√3) simplifying to 2d / √3.
