Question

A 25 - foot ladder is leaned against a wall. If the base of the ladder is 7 ft from the wall,

how high up the wall will the ladder reach?

Answer 1

24 feet

Explanation:

Answer 2

24

Explanation:

Since the ladder, wall, and ground form a right triangle, you can use this formula:

A squared + B squared = C squared

A = 7 feet

C = 25 feet

B = distance the ladder will reach

49 + B squared = 625

B squared = 625 - 49

B = square root of 576

B = 24 feet
