# Play with triangle

Geometry Level 4

If the bisector of the angle A of triangle ABC meets BC in D, then $$a$$ = $$(b+c){[1-\frac{{AD}^{x}}{bc}]}^{y}$$ where $$a$$, $$b$$ & $$c$$ are the length of sides opposite to angle A, B & C respectively and $$x$$ & $$y$$ are rational numbers. Find the value $$xy$$.
