Hence, the height of the kite from the ground is 75 m.
A ladder 15 m long just reaches the top of a vertical wall. If the
ladder makes an angle of 60° with the wall, find the height of
the wall.

Let OX be the horizontal ground and let OA be the ladder
leaning against the wall AB. Then,
OA= 15 m, ZOAB = 60° and
ZOBA= 90°.
600
Let AB=h metres.
Now, ZAOB=(90° -60°) = 30°.
Х
iht AOBA, we have
