2019 AIME I Problem 15

Let \overline{AB} be a chord of a circle \omega, and let P be a point on the chord \overline{AB}. Circle \omega_1 passes through A and P and is internally tangent to \omega. Circle \omega_2 passes through B and P and is internally tangent to \omega. Circles \omega_1 and \omega_2 intersect at points P and Q. Line PQ intersects \omega at X and Y. Assume that AP=5, PB=3, XY=11, and PQ^2 = \tfrac{m}{n}, where m and n are relatively prime positive integers. Find m+n.

Leading zeroes must be inputted, so if your answer is 34, then input 034
