  1. Question 1

    Q1. The angle of elevation of the top of a tower from a point on the ground is 45°. If the distance from the point to the foot of the tower is 30 m, find the height of the tower.

    • A) 30 m
    • B) 30√2 m
    • C) 30/√2 m
    • D) 60 m

    Answer: 30 m

    Explanation: Using tan(45°) = height / 30, we get height = 30 m since tan(45°) = 1.
