From a point P on a level ground, the angle of elevation of the top tower is 30°. If the tower is 100 m high, the distance of point P from the foot of the tower is:
Answer: Option
Explanation:
Let AB be the tower.
Then, 
APB = 30° and AB = 100 m.
| AB | = tan 30° = | 1 |
| AP | 3 |
 AP |
= (AB x 3) m |
| = 1003 m | |
| = (100 x 1.73) m | |
| = 173 m. |
