Question

A tree is broken at a height of 5m from the ground and its top touches the ground at a distance of 12 m from the base of the tree. Find the original height of the tree.

Answer 1

18 m

Step-by-step explanation:

as shown in the figure

we simply apply Pythagoras theorem and we get, (5)²+(12)²=x² (let the rest side =x)

so now, 25+144=x²

169=x²

as we know 169 is a square of 13

so x=13

and the total height of tree= 13 +5=18m
