There are three circles, all of them touching each other. The bottom two circles are laying on an imaginary floor, such that they touch the line g=-r as well.
Given are all three radii, r1 (A), r2 (B) and r3 (C). Assuming circle A has its center on (0/0), B has its center on (2 sqrt(r1 * r2), r2 - r1). I am now supposed to find the coordinates of C.
Is this a know problem and has an easy/straighforward solution? I can't seem to find a nice approach.
