The angle of elevation of the top of a tower from a point on the ground is 45°. If the tower is 20 meters high, find the distance of the point from the base of the tower.
Show answer & explanation
Correct answer: A
Explanation
Height of the tower = 20 meters
Angle of elevation = 45°
tan45° = Height / Base
1 = 20 / Base
Base = 20 meters
