$s41resh$ is having a garden near Delhi. In
the garden, there are different types of
trees and flower plants. One day due to
heavy rain and storm one of the trees got
broken as shown in the figure.
The height of the unbroken part is $15m$
and the broken part of the tree has fallen
at 20 m away from the base of the tree.
