  1. Question 1

    Q1. From the top of a tower, the angle of depression of a point on the ground is 45°. If the height of the tower is 20 m, find the distance of the point from the foot of the tower.

    • A) 20 m
    • B) 10 m
    • C) 20√2 m
    • D) 10√2 m

    Answer: 20 m

    Explanation: Using tan(45°) = 20 / distance, we get distance = 20 m.
