Question

KINDLY ANSWER
A fire person needs to use a ladder of 25 feet in length to rescue a cat that has become stuck in a tree. The tree is 50 feet high, and the cat is 15 feet off the ground straight up in the trunk of the tree. How far from the bottom of the tree will the ladder have to be in order to reach the point at which the cat is?

Answer 1

length of ladder=25ft

cat is at height of 15ft

From pythogoras theorem

(25)^2=(15)^2+X^2

625-225=400=X^2

X=20

The distance at which the ladder is to be put from tree is 20ft

Answer 2

The answer is 20 ft.
