  1. Question 1

    Q1. A tower stands at the center of a circular park. A and B are two points on the boundary such that AB = d subtends an angle 60° at the foot of the tower, and the angle of elevation of the top of the tower from A or B is 30°. Find the height of the tower.

    • A) d/√3
    • B) d√3
    • C) d/3
    • D) d/2

    Answer: d/√3

    Explanation: Relating the triangle formed by A, B, and the tower's base to the height using trigonometric ratios, height = d/√3.
