The angles of elevation of the top of a tower from two points on the ground 9 m and 4 m away from its foot are complementary. What is the height of the tower?
Q1. The angles of elevation of the top of a tower from two points on the ground 9 m and 4 m away from its foot are complementary. What is the height of the tower?
Answer: 6 m
Explanation: Using tan(θ) = h / 9 and tan(90°-θ) = h / 4, we get h² = 36, hence h = 6 m.
