alleryA tower stands vertically on the ground. The angle of elevation of its top from a point 30 m away is 60 degrees. The height of the tower is
A30 m
B30 (square root of 3) m
C15 (square root of 3) m
D60 m
Answer & Solution
Correct answer: B. 30 (square root of 3) m
1. tan(60) = h / 30.
2. tan(60) = square root of 3.
3. h = 30 (square root of 3) m.
