A) By the angle bisector theorem, BC = 32/7.

 

B) Again by the angle bisector theorem, BZ = 11/3.

1)    The angle bisector theorem:    CY / AY = BC / AB

 

                                                    4 / 6 = BC / 8

 

                                                     BC = 5.333333

 

2)    Using a Law of cosines calculate angles C  and  B

 

3)    Use the Law of sines to calculate BZ

 

Geometry is fun.laugh
