Chapter 9, Problem 7RP

To determine

To find:The distance of foot of the ladder from the wall

Answer to Problem 7RP

The distance of foot of the ladder from the wall is $7\text{ ft}$

Explanation of Solution

Given information:The following information has been given

The length of the ladder is $25\text{ ft}$

The height of the wall where it reaches is $24\text{ ft}$

We apply the Pythagoras theorem in the right triangle formed, thus we get

  ${24}^2+x^2={25}^2$

Hence, we get

  $x=7\text{ ft}$
