# The angle of elevation of the top of a tower from a point on the ground which is...

### Question

The angle of elevation of the top of a tower from a point on the ground which is 36m away from the foot of the tower is 30o. Calculate the height of the tower.

A) 62.35m

B) 20.78m

C) 18.00m

D) 10.39m

### Explanation:

Where H is the height of the tower H = ?
$$Tan 30^{\circ} = \frac{H}{36} \Rightarrow H = 36 \times tan30^{\circ}\\H = 36 \times 0.5774 = 20.79$$

## Dicussion (1)

• Where H is the height of the tower H = ?
$$Tan 30^{\circ} = \frac{H}{36} \Rightarrow H = 36 \times tan30^{\circ}\\H = 36 \times 0.5774 = 20.79$$
