Two circles intersect and have a common chord that is 36 inches long. The distance between the centers of the circles is 104 inches. If one circle has a radius of 82 inches, find the radius of the other circle.

Simplify. 4+3/7x-2-2/7x a. 2-5/7x b. 6-1/7x c. 2+1/7x d. 6+5/7x

In the diagram, ab is tangent to c, ab = 4 inches, and ad = 2 inches. find the radius of the circle.
