Question
The angle of elevation of a pole from a point, which is
20 m away from the foot of the pole is 45°. Find the height of the pole.Solution
Angle of elevation = 45° Distance of the bottom of the pole from a point = 20m In triangle ABC, AB/BC = tan45° ⇒ h/20 = 1 ∴ The height of the pole = h = 20 m
