  1. Question 1

    Q1. A man standing on a cliff observes a boat at an angle of depression of 30°. If the cliff is 50m high, how far is the boat from the cliff?

    • A) 50√3 m
    • B) 60√3 m
    • C) 70√3 m
    • D) 86.6 m

    Answer: 50√3 m

    Explanation: tan(30°) = 50 / distance. So, distance = 50 / tan(30°) = 50 / (1/√3) = 50√3 m.
