AF = sinB * c

 

BF = AF / cosB 

 

CF = sqrt(b2 - AF2)

 

BC = BF + CF

 

When you have all 3 sides, use the law of cosines to calculate the other 2 angles.

I made an error in the 2nd row:     (BF = AF / cosB) wrong!

                                                       

                               should be:      BF = AB * cosB
