Using the Law of Sines, we have

 

sin P / 47.6  =  sin 73 / 68     multiply both sides by 47.6

 

sin P  = ( 47.6 sin (73) / 68 )

 

Take the sine inverse to find  P

 

arcsin  ( 47.6 sin (73) / 68 )  = P  ≈   42.02°

 

 

 

Using the Law of Cosines

 

d =  sqrt [ 21^2 + 27^2 - 2(21)(27)cos(25) ]  ≈  11.93
