A 10 ft long ladder has one end that leans against a wall and another that rests on the ground 6 feet from the wall. To find out how high on the wall the ladder rests, which of the following formulas would be used?
Distance Formula
Slope Formula
Pythagorean Theorem
None of these choices are correct.

Pythagorean Theorem

Step-by-step explanation:

A 10 ft long ladder has one end that leans against a wall and another that rests on the ground  - hypotenuse

6 feet from the wall - one leg

how high on the wall the ladder rests - second leg.

We have a right triangle, we need to find a leg,

so we have to use

Pythagorean Theorem.
