  1. Question 1

    Q1. A man observes the angle of elevation of the top of a tower to be 45°. He walks towards it in a horizontal line through its base. On covering 100 m, the angle of elevation changes to 60°. The height of the tower is

    • A) 236.6 m
    • B) 150 m
    • C) 200 m
    • D) 250 m

    Answer: 236.6 m

    Explanation: Using trigonometric relations for the two angles of elevation, we derive the height of the tower.
