Question

A ladder is leaning against a vertical wall. The distance from the top of

the ladder to the base of the wall is 8 feet. The length of the ladder is
23 feet. What is the distance from the base of the wall to the bottom of
the ladder (nearest tenth)?

Answer 1

x = 21.6 ft

Explanation:

Using the Pythagorean Theorem, 23² = 8² + x²

529 - 64 = 465

465 = x²

21.6 = x
