  1. Question 1

    Q1. A person observes a tower at an angle of elevation of 45° from a distance. On walking 100 m closer, the angle becomes 60°. What is the height of the tower?

    • A) 50(3 + √3) m
    • B) 50(3 - √3) m
    • C) 100(3 + √3) m
    • D) 100(3 - √3) m

    Answer: 50(3 + √3) m

    Explanation: Using the tangent function for both angles of elevation and the distance walked, we form two equations to solve for the height of the tower, applying trigonometric ratios.
