See below.

Explanation:

sin(A)/(BC)=sin(B)/(AC)

Substitute the known stuff,

sin(54)/(14)=sin(82)/(b)

Plug the information into a calculator to get that:
b=17

17 inches

Explanation:

There are two sides opposite two given angles.

Use the Sine rule

b/sin82 =14/sin54

b = (14 sin82)/sin54

b=17.137

A bit of reasoning:
Sides with longer lengths are opposite larger angles.

Explanation:

Since 82 > 54, the side opposite the larger angle must have a measure greater than 14". The only one of the choices that fits that criterion is 17".
