  1. Question 1

    Q1. A tower subtends an angle of 30° at a point on the same level as the foot of the tower. At a second point, h m above the first, the depression of the foot of the tower is 60°. The height of the tower is

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

    Answer: h/3 m

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