  1. Question 1

    Q1. A 2m tall man is standing 10m away from a tower. The angle of elevation of the top of the tower from his eyes is 60°. How tall is the tower?

    • A) 15.32 m
    • B) 17.32 m
    • C) 19.32 m
    • D) 21.32 m

    Answer: 19.32 m

    Explanation: tan(60°) = (h - 2) / 10. So, h - 2 = 10 * √3. Thus, h = 10√3 + 2 = 19.32 m.
