first find angle B:

then angle C is
C=180-(25.07+78.8898 )
C=76.04°

and side c

c=21.76

Where did you get 25.07?
I thought 25° + (4/60)' is 25.1°, right? Am I converting the wrong way? In my calculations, 25° 4' = 25.1°. No?

4/60=1/15=0.0666666666666667=0.07

25° + 0.07°=25.07°

4/60=1/15=0.0666666666666667=0.07

25° + 0.07°=25.07°

I see this is another case of making careless mistakes with simple math on my part.
