We can help. What sort of help do you need? What have you tried? What happened?
In order to give an appropriate hint, we need to know what you have learned. Are you doing trigonometry, including solving triangles? How about cyclic quadrilaterals? Or would you like to use coordinate geometry? Possibly this is meant to exercise some particular topic you just learned. Let us know.
