Problem Statement

Triangle ABC\vartriangle ABC has sidelengths AB=10AB = 10, AC=14AC = 14, and, BC=16BC = 16. Circle ω1\omega_1 is tangent to rays AB\overrightarrow{AB}, AC\overrightarrow{AC} and passes through BB. Circle ω2\omega_2 is tangent to rays AB\overrightarrow{AB}, AC\overrightarrow{AC} and passes through CC. Let ω1\omega_1, ω2\omega_2 intersect at points X,YX, Y . The square of the perimeter of triangle AXY\vartriangle AXY is equal to a+bcd\frac{a+b\sqrt{c}}{d} , where a,b,ca, b, c, and, dd are positive integers such that aa and dd are relatively prime, and cc is not divisible by the square of any prime. Find a+b+c+da + b + c + d.
