(In reply to The issue
I try also and arrived at your third solution.
In my opinion the intended solution was X/Y=17/sqrt2 (12,0208...) with PQ=17
In that case the coordinates of U [R=(0,0)] should be (5,469; 2,466).
But probably some calculator shift occurs as the smart numbers are very close to the analytic solution.
