  1. Question 1

    Q1. A tower stands vertically on the ground. From a point on the ground, 20 m away, the angle of elevation to the top is 45°. What is the tower's height?

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

    Answer: 20 m

    Explanation: Using tan(45°) = height / 20, we get height = 20 m since tan(45°) = 1.
