Problem 10.5 Let P and Q be points on the side AB of the triangle ABC (with P between A and Q) such that ZACP = ZQCB, and let AD be the angle bisector of ZBAC. Line AD meets lines CP and CQ at M andN respectively. Given that PN = CD and 3ZBAC = 2ZBCA, prove that triangles CQD and QNB have ZPCQ the same area.
