A pole 81m high broke at a point but did not separate.Its top touched the ground 27 m from its base.At what height above the ground did the pole break?

suppose the point from which the pole broke is *x* meters above the ground.Then the length of AC will be (81-*x)m.*

ΔABC is right angled triangle. By applying Pythagoras theorem ,

Height from which the pole broke is 36 meters above the ground.
