Let $ ABC $ be an acute-angled triangle in which $ \omega $ is its circumscribed circle, and $ H $ is the orthocenter. The tangent to the circumscribed circle of $ \triangle HBC $ at the point $ H $ intersects $ \omega $ at the points $ X $ and $ Y $. It turned out that $ HA = 3 $, $ HX = 2 $, $ HY = 6 $. The area of $ \triangle ABC $ can be written as $ m \sqrt n $, where $ m $ and $ n $ are natural numbers and $ n $ is not divisible by the square of any prime number. Find the value of $ m + n $.
