Answer: The correct option is (D) 173 m.
Step-by-step explanation: Given that from a point P on a level ground, the angle of elevation of the top tower is 30 degrees and the tower is 100 m high.
We are to find the distance of the point P from the foot of the tower.
The picture is shown in the attached figure below. AB is the height of the tower and BP is the distance of the point P from the foot of the tower B.
The triangle ABP will be a right angled triangle, where
Using the trigonometric ratios, we have
Thus, the distance of point P from the foot of the tower is approximately 173 meters.
Option (D) is CORRECT.
