A painter leans a 20 foot ladder against a house so that it touches the house 11 feet from the ground. How far from the base of the house does the ladder rest on the ground?

This problem involves using the Pythagorean Theorem which is a^2+b^2=c^2

We already have the values of a and c, but b is unknown. So we plug in: 11^2+b^2=20^2

121+b^2=400

b^2=279

b=sqrt(279)

b=16.7

So the answer is about 16.7 ft

Hope this helped!

answer: i think one of the answer is $150 and $300?
