Finishing the answer above:
B=36
a=38
c=18
b=25.7
a-b-c (SSS) {a^2=b^2+c^2-2ab(CosA) [Law of Cosines]
38^2=25.7^2+18^2-2(25.7)(18)(CosA)
1444=660.49+324-925.2(CosA)
1444=984.49-935.2(CosA)
459.51=-935.2(CosA)
-0.491349443969204=CosA
A=119.43
b-B-C (SAA) {(SinC)/c=(SinB/b)} [Law of Sines]
(SinC)/18=(Sin36)/25.7
(SinC)/18=0.022871021489979
SinC=0.411678386819631
C=24.31
A=119.43
B=36
C=24.31
a=38
b=25.7
c=18
