A ladder 15 m long just reaches the top of a vertical wall. If the ladder makes an angle of 60^{0} with the wall, then find the height of the wall.

Given: length of ladder = 15 m

Angle between the ladder and the top of the wall = 60°

We have to find the height of the wall, h.

In

Thus, the height of the wall is 7.5 m.
