  1. Question 1

    Q1. A man is standing on a bridge, and the angle of depression to a boat is 60°. If the height of the bridge is 20 m, find the distance between the bridge and the boat.

    • A) 20/√3 m
    • B) 20√3 m
    • C) 10 m
    • D) 40 m

    Answer: 20/√3 m

    Explanation: Using trigonometric ratio: tan(60°) = 20 / distance, so distance = 20 / √3 m.
