Answer by rothauserc(4718) (Show Source): You can put this solution on YOUR website!
we use the law of sines, that is
(a/sin(A)) = (b/sin(B)) = (c/sin(C))
we are given
(34/sin(46)) = (27/sin(B))
34sin(B) = 26sin(46)
34sin(B) = 18.702834809
sin(B) = 0.550083377
note use inverse sin function to find angle B
B = 33.372733167 approx 33.4 degrees then
C = 180 - (46 + 33.4) = 100.6
************************************************
(b/sin(B)) = (c/sin(C))
27/0.550083377 = c/0.982935349
0.550083377 * c = 27 * 0.982935349
0.550083377 * c = 26.539254427
c = 48.245876056 approx 48.2
therefore
*************************************************
A=46 degrees, B=33.4 degrees, C=100.6 degrees
a=34, b=27, c=48.2
