Ortocentričan sistem | Ortocentric system #4

Neka je ABC šiljastokutan trokut s opisanom kružnicom k i ortocentrom H. Pretpostavimo da pravac tangentan na opisanu kružnicu trokuta \triangle HBC u H siječe k u točkama D i E tako da vrijedi |AH|=3, |DH|=2, |EH|=6. Nađi površinu \triangle ABC.
Let ABC be an acute triangle with circumcircle k and orthocenter H. Suppose the tangent to the circumcircle of \triangle HBC at H intersects k at points D and E with HA=3, HX=2, HY=6. Find the area of \triangle ABC.
