Q10 of 120 Page 95

A ladder 15 m long just reaches the top of a vertical wall. If the ladder makes an angle of 600 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.
