A Tangent Through the Orthocenter

Problem

Let ω\omega be the circumcircle of an acute triangle ABCABC with orthocenter HH. The tangent line at HH to the circumcircle of HBC\triangle HBC meets ω\omega at points XX and YY. Given HA=3HA=3, HX=2HX=2, HY=6HY=6, the area of ABC\triangle ABC in simplest form is mnm\sqrt n, where mm and nn are positive integers and nn is squarefree. Find m+nm+n.
