Q18 of 68 Page 9

A ladder is placed against a vertical wall such that it just reaches the top of the wall. The foot of the ladder is 1.5 m away from the wall and the ladder is inclined at an angle of 60° with the ground. Find the height of the wall.

Drawing a diagram for better understanding of the problem,



We know that from trigonometric ratios that,





height of vertical wall = 1.5√3m


Therefore, the calculated height of vertical wall is 1.5√3m.
