What am I missing? I have a feeling that the M is midpoint part is crucial. But how?
Thanks for all your help!
Here is a hint: Prove that the midpoint of the hypotenuse of a right triangle is equidistant from the vertices.
It then follows that XZ = 13 and so XY = 12 is easily obtained.

Fantastic! :) I completely blanked out on that. I have been using "Diameter subtends a right angle on circle", but didn't think of using it in reverse. Thanks a lot, a very elegant problem and solution.
