  1. Question 1

    Q1. A man observes the angle of elevation of the top of a tower to be 30°. If he walks 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) 173.2 m

    Answer: 86.6 m

    Explanation: Using tan 30° and tan 60°, we form two equations and solve for height, applying trigonometric identities for right triangles.
