  1. Question 1

    Q1. The angle of depression from the top of a 20 m high cliff to a ship is 30°. How far is the ship from the cliff's base?

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

    Answer: 20√3 m

    Explanation: Using tan(30°) = 20 / distance, we get distance = 20 / tan(30°) = 20√3 m.
