  1. Question 1

    Q1. The angle of elevation of the top of a tower from a point on the ground is θ. If the height of the tower is h, find the distance of the point from the tower when θ = 45°.

    • A) h m
    • B) h / 2 m
    • C) h √3 m
    • D) h / √3 m

    Answer: h m

    Explanation: tan 45° = h / distance. So, distance = h m.
