  • Answer

Let ω1\omega_{1} and ω2\omega_{2} be two non-intersecting circles. Suppose the following three conditions hold:

  • The length of a common internal tangent of ω1\omega_{1} and ω2\omega_{2} is equal to 19 .
  • The length of a common external tangent of ω1\omega_{1} and ω2\omega_{2} is equal to 37 .
  • If two points XX and YY are selected on ω1\omega_{1} and ω2\omega_{2}, respectively, uniformly at random, then the expected value of XY2X Y^{2} is 2023 .

Compute the distance between the centers of ω1\omega_{1} and ω2\omega_{2}.
