A school boy lying on the ground 30m away from the foot of a water tank tower observes that the angle of elevation of the top of the tank 60o. Calculate the height of the water tank.
- 60m
-
30 \(\sqrt{3}\)m
- 20 \(\sqrt{3}\)m
- 10 \(\sqrt{3}\)m
The correct answer is: B
Explanation
h = 30 tan 60o= 30\(\sqrt{3}\)
