  1. Question 1

    Q1. The angle of elevation of the top of a hill at the foot of a tower is 60°. After ascending 'h' meters up the tower, the angle of elevation becomes 30°. If the height of the tower is 'H', find 'h' in terms of 'H'.

    • A) H / 2
    • B) H / √3
    • C) H(√3 - 1) / √3
    • D) H(2 - √3)

    Answer: H(√3 - 1) / √3

    Explanation: Using trigonometric ratios and the given angles, we can form equations to solve for 'h' in terms of 'H'.
