  1. Question 1

    Q1. A man observes the angle of elevation of a tower to be 30°. After walking 100 m towards the tower, the angle becomes 60°. Find the height of the tower.

    • A) 50√3 m
    • B) 86.6 m
    • C) 100 m
    • D) 200 m

    Answer: 86.6 m

    Explanation: Using trigonometric ratios, tan(30°) = h / (x + 100) and tan(60°) = h / x. Solving these, we get h = 86.6 m.
