Question

Your friend has locked themselves out of the house, and they need your help to get back in. They have a 15 foot long ladder, and there is an open window 12 feet above the ground. How far from the of should you hold the ladder while they climb back in

Answer 1

w = 9 feet far you should hold the ladder while they climb back in

Let the length be $l$ = 15 feet and open window feet above the ground be k= 12 feet

The value of w will be given by the Pythagoras theorem,

Pythagoras theorem: In a right-angled triangle, the square of the long side is equal to the sum of the squares of the other two sides.

It is stated in this formula:

$w^{2} =l^{2}- k^{2} \\\\w^{2}= 15^{2}- 12^{2} \\\\w^{2} = 225-144\\\\w^{2} = 81\\\\w=9$

Hence,  w = 9 feet far you should hold the ladder while they climb back in.
