Brianna is shopping for a new cell phone provider. in her city there are three providers: Company a company b company c. cell phone radio towers broadcast a cell phone signal in a circular pattern. The table below shows the location of the cell phone towers for the three companies as well as the coverage radius.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
