  1. Question 1

    Q1. The angle of depression of a boat from the top of a cliff 100 m high is 30°. How far is the boat from the foot of the cliff?

    • A) 100√3 m
    • B) 50√3 m
    • C) 200 m
    • D) 100 m

    Answer: 100√3 m

    Explanation: Using tan(30°) = 100 / distance, we get distance = 100√3 m since tan(30°) = 1/√3.
