Arlington is 7.9 miles due north of the airport, and Manchester is 5.7 miles due east of the airport. How far apart are Arlington and Manchester? If necessary, round to the nearest tenth.
Using Pyhthagoreon Theorm we know that the distance of the two cities=x
7.9^2+5.9^2=(the distance of the two cities)
So the distance from arlington and manchester is 10 miles
