A vertical tower casts its gaze upwards from the ground. If you stand 30 meters from its base and look up at a 30-degree angle to its peak, how tall is the tower?
Show answer & explanation
Correct answer: D
Explanation
Distance from the base of the tower = 30 meters
Angle of elevation = 30°
Let the height of the tower = h
tan30° = Height / Base
1/√3 = h / 30
h = 30/√3 = 10√3 meters
