From the top of a 50 m tower, the angle of depression of two objects on the same side of the tower are 45 and 60. Find the distance between the objects.
Show answer & explanation
Correct answer: A
Explanation
Height = 50 m
Near object (60°): Distance = 50 / √3 = 50√3 / 3
Far object (45°): Distance = 50 / 1 = 50
Intermediate distance = 50 − 50√3/3
≈ 50 − 28.87 = 21.13 m
