Apainter places an 11-ft ladder against a house. the base of the ladder is 3 ft from the house. how high on the house does the ladder reach?

The ladder reach 10.58 feet

Step-by-step explanation:

In this problem a rectangle triangle is formed, with hypotenuse = 11 feet, a side = 3 feet and the other side is the unknown, i. e., how high on the house the ladder reach.  

From Pythagorean theorem:

hypotenuse^2 = side^2 + side^2

11^2 = 3^2 + side^2

side^2 = 11^2 - 3^2

side = sqrt(112)

side = 10.58 feet
