1.  From a point P on a level ground, the angle of elevation of the top tower is 30º. If the tower is 100 m high, the distance of point P from the foot of the tower is:

A. 149 m
B. 156 m
C. 173 m
D. 200 m

Answer: Option C

Explanation:

Let AB be the tower.

Then, APB = 30º and AB = 100 m.

AB = tan 30º = 1
AP 3

AP = (AB x 3) m
= 1003 m
= (100 x 1.73) m
= 173 m.
