SOLUTION: Using the law of Cosine or Sine, solve:
a=60 b=x c=20 Angles A=x B=x C=34.0 degrees SSA
I tried A=sin-1(60sin34.0/20) but it said error. Pleas help

Answer by scott8148(6628) (Show Source): You can put this solution on YOUR website!
the law of sines says that the ratio between the sine of an angle and the length of the opposite side
is constant in a triangle
so a/sin(A)=b/sin(B)=c/sin(C)
use c, C, and a to find A ... then B=180-A-C ... then find b
