Answer:

Step-by-step explanation:

base of ladder is x feet from house

top of ladder is x+1 feet from ground

By the Pythagorean Theorem,

x² + (x+1)² = 5²

x² + (x² + 2x + 1) = 25

2x² + 2x - 24 = 0

x = -4, 3

-4 is an extraneous solution, so x = 3 ft

base of ladder is 3 feet from house

top of ladder is 4 feet from ground
