What have you tried? What have you learned? We can't help a lot without knowing that.

The problem itself is odd in several ways. Point F is not even on quadrilateral ABCX! Lines AF and CF are poorly drawn. I would start by redrawing the figure; in particular, I would take into account the angle bisector, which tells you some useful things.
