Question

A 10-foot ladder leans against a wall. It hits the wall 9 feet up. How far is the base of the ladder from the wall? Apply the Pythagorean Theorem to this problem

Answer 1

square root of 19

Explanation:

10^2 - 9^2 = 19

Answer 2

4.4 ft

Explanation:

10^2=9^2+b^2

100=81+b^2

Subtract 81 from both sides

19=b^2

Take the square root of both sides

√19=b or 4.4=b
