Q11 of 158 Page 159

The top of a broken tree touches the ground at a distance of 12 m from its base. If the tree is broken at a height of 5 m from the ground then the actual height of the tree is

Given: Height of broken tree = 5m


Base distance of tree touch the ground = 12cm


Formula Used/Theory:-


Pythagoras theorem:-


Base2 + Height2 = Hypotenuse2


Length of broken tree is :-


Base2 + Height2 = Hypotenuse2


122 + 52 = Hypotenuse2


144 + 25 = Hypotenuse2


169 = Hypotenuse2


Height of broken tree = √ 169 = 13m


Height of tree = length of broken tree + 5m


= 13m + 5m = 18m
