**Steve**, Thursday, May 15, 2014 at 5:54amwell, we know that with center at (h,k) the circle's equation is

(x-h)^2 + (y-k)^2 = 100

Since (20,10) is on the circle, at one end of the horizontal diameter, it is clear that the center of the circle is at (10,10).

(x-10)^2 + (y-10)^2 = 100

Getting the triangle's dimensions should now be no trouble.
