The angle of elevation of the top X of a vertical pole from a point P on a level ground is 60o. The distance from P to the foot of the pole is 55m. Without using tables, find the height of the pole.
Answer Details
We can use trigonometry to solve this problem. Let's draw a diagram to help us visualize the situation:

P
We know that the angle of elevation of X from P is 60 degrees, which means that the angle XPX' is also 60 degrees, where X' is the foot of the pole. We also know that the distance from P to X' is 55m.
Let H be the height of the pole. Then we have:
tan 60 = H / PX'
We can simplify this expression using trigonometric ratios:
√3 = H / 55
Solving for H, we get:
H = 55√3
Therefore, the height of the pole is 55√3 meters. So the correct option is (c).
