  1. Question 1

    Q1. The top of a tower is observed from two points on the ground, 20 m apart, at angles of elevation 30° and 60°. Find the height of the tower.

    • A) 10√3 m
    • B) 20√3 m
    • C) 10 m
    • D) 20 m

    Answer: 10√3 m

    Explanation: Let the height be h. Using tan(60°) = h / x and tan(30°) = h / (x + 20), we can solve for h to get 10√3 m.
