A ladder is leaning against a vertical wall. The distance from the base of the wall to the bottom of the ladder is 21 feet. The lengtj of the ladder is 25 feet. What is the distance from. The base to the ladder?

13.6 feet from the wall

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 + b² = c²

a² + 21² = 25²

a² + 441 = 625

-441 - 441

a² = 184

√ √

√a² = √184

b = 13.6
