In figure given two sides and the included angle (SAS) so we can apply cosine rule.
[tex]b^{2}=a^{2}+c^{2}-2accosB.[/tex]
In the figure a=22,c=14,<B=110°
Substituting these values in cosine formula :
[tex]b^{2}=22^{2}+14^{2}-2(22)(14)cos 110 .[/tex]
[tex]b^{2}=484+196-616(-0.34)[/tex]
[tex]b^{2}=680+209.44[/tex]
[tex]b^{2}=889.44[/tex]
b=29.84.
Option A is the right answer.
