comment Solve a trig equation system
@Guesswhoitis. a,b,c are constant value. For example,when PA=3,PB=4,PC=5, NMaximize[{Sqrt[a^2+b^2-2a b Cos[A+B]]+Sqrt[b^2+c^2-2b c Cos[A]]+Sqrt[c^2+a^2-2c a Cos[B]] /. {a->3,b->4,c->5},0<A<Pi,0<B<Pi},{A,B}] return 20.9323 (Root[16257024-3869200 #1^2-1568639 #1^4+3600 #1^6 &, 4])
