  1. Question 1

    Q1. If the angle of elevation of the top of a tower is 30° at a point 100 m away, find the height of the tower.

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

    Answer: 100/√3 m

    Explanation: tan(30°) = height / 100, so height = 100 * tan(30°) = 100 * 1/√3 = 100/√3 m.
