  1. Question 1

    Q1. The angle of elevation of the top of a tower from a point 100 m away is 30°. Find the height of the tower.

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

    Answer: 100√3 m

    Explanation: Using tan(30°) = height / 100, we get height = 100 * tan(30°) = 100 / √3 * √3 / √3 = 100√3 / 3, simplifying we use tan(30°) = 1/√3.
