The bottom of a 13 foot straight ladder is the into the ground 5 feet away from a wall when the top of the ladder is leaned against the wall what is the distance above the ground it well reach

12 feet

Step-by-step explanation:

This is a Pythagorean theorem question

The ladder is the hypotenuse or c

the distance from the wall is a leg or a

and the wall is the other leg or b

a² +  = c²

5² + b² = 13²

25 + b² = 169

-25          -25

         b² = 144

         √        √

         √b² = √144

           b = 12

answer: .64
