Answer:
Step-by-step explanation:
because c is shorter than a we know C is a smaller angle than A
so the first choice is out.
use the law of cosines to find b
[tex]b^{2}[/tex] = [tex]a^{2} +c^{2} -2*a*c*cos(B)[/tex]
[tex]b^{2}[/tex] =1681+400-1326.787871
[tex]b^{2}[/tex]= 754.21219
b= [tex]\sqrt{754.21219}[/tex]
b= 27.46292
so the last choice looks good
