Question
The angle of depression of a point on the ground as seen
from the top of a tower, 20 feet high, is 45°. Find the distance of the point on the ground from the foot of the tower.Solution
Let θ be the angle of depression of the point on the ground as seen from the top of a tower, here θ = 45° Let AC be the height of the tower, here AC = 20 feet. Let the distance of the point on the ground from the foot of the tower, AB = x feet. Here, tan θ = AC/AB ⇒ tan 45° = 20/x ⇒ 1 = 20/x ⇒ x = 20 feet
