Acell phone company is looking to place a new tower to service 3 cities. in order for it to best service each city, it needs to be equidistant from all 3 cities. what mathematical concept could they use to find a location that is equidistant from all 3 cities? why is this a good method?

Step-by-step explanation:

The circumscribed circle or circumcircle of a polygon is a circle that passes through all the vertices of the polygon. The center of the circle, the circumcenter, is equidistant from all of the polygon's vertices.

The center is found at the point of intersection between the perpendicular bisectors of any two (non-parallel) chords of the circle. That is, the perpendicular bisectors of any two of the sides of the triangle joining the cities will intersect at the circumcenter.

The method of locating the center of the circle this way is simple and effective.

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
