ok, first off, damn u for making me think on a saturday, second i didnt read the other solutions so i dunno if someone already solved it, and third im too lazy to solve it, but ill tell u how.
all u need to do is find the equations of the circles and the rest is easy. to do this, just imagine two circles, which is the top circle and the left circle in ur graph. now let the x axis be in the middle, and the y axis be in middle as well.
(x-36.251)^2 + y^2 = 1853.91 <---big circle
x^2 + (y-a)^2 = 5.029 <---little circle
note*: a is the distance from x axis to the centre of the little circle
now at the interection point, we can equate these to get two equations, since theres 3 unknown, we derive both and set them equal (cuz slopes are same at that point) and once we solve for a, we have eations and we done.
