  1. Question 1

    Q1. The angle of depression from a lighthouse top to a ship is 30°. If lighthouse height is 50m, find horizontal distance to the ship.

    • A) 50√3 m
    • B) 100 m
    • C) 50 m
    • D) 25√3 m

    Answer: 50√3 m

    Explanation: tan(30°) = 50 / distance, so distance = 50√3 m, using trigonometric ratio for right triangle.
