Marty leaves his house and walks 5 miles due west. He stops at the library and then walks 8 miles due north. HOW FAR IS Marty from his house? Round your answer to the nearest tenth. Graph and show work.
-----------------
You can make a right triangle with sides of 5 and 8 miles.
The hypotenuse is sqrt(5^2 + 8^2) = sqrt (89)
sqrt (89) = ~ 9.4 miles
