2020 AIME II Problem 15

Let \triangle ABC be an acute scalene triangle with circumcircle \omega. The tangents to \omega at B and C intersect at T. Let X and Y be the projections of T onto lines AB and AC, respectively. Suppose BT = CT = 16, BC = 22, and TX^2 + TY^2 + XY^2 = 1143. Find XY^2.

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