  1. Question 1

    Q1. The angles of elevation of the top of a tower from two points at a distance of 4 m and 9 m from the base of the tower and in the same straight line with it are complementary. Find the height of the tower.

    • A) 6 m
    • B) 5 m
    • C) 7 m
    • D) 8 m

    Answer: 6 m

    Explanation: Using tan(θ) = h / 9 and tan(90° - θ) = h / 4, h² = 36, h = 6 m.
