Question

Help please. Im giving 20 points.

In Belleville, the library is due south of the courthouse and due west of the
community swimming pool. If the distance between the library and the courthouse
is 9 miles and the distance between the courthouse and the city pool is 15 miles,
how far is the library from the community pool?

Answer 1

The distance is 144

Explanation:

We solve this by using the Pythagorean Theorem.

Using the equation: a squared + b squared= c squared.

In this case, 9 squared + b squared = 15 squared.

So 81+b squared = 225

-81 -81

b= 144
