Question

Jason leans a 12 foot ladder against the side of his house with the base of the ladder 3.5 feet from the house. To the nearest tenth, how high up the side of the house does the ladder reach?

Answer 1

`11.5`

Explanation:

This is a Pythagorean Theorem question. The hypotenuse is 12 and the base is 3.5

`12^2-3.5^2=144-12.25=131.75`
`sqrt(131.75)~~11.5`
