1, solve triangle ABC which have angleA= 250.251 angleB=600.511 and a=3.82 find c
How about you give us some angles that make sense in a triangle.
The angles need to sum to 180. I realize that C is unknown, but geez, guy. What system are you using?
Anyway, assuming you can actually devise some reasonable values, just use the law of sines:
a/sinA = c/sinC
c = a*sin(180-A-B)/sinA
