Answer:

23.01 = b

Step-by-step explanation:

Solve this using the Law of Cosines first:  Find side length b.

b^2 = 22^2 + 28^2 - 2(22)(28)*cos 34 deg, or:

b^2 = 484   +  784   - 2(616)(0.593), or

       =       1260    -730.576    =    529.424

Taking the square root of both sides, we get:

b = +√529.424 = 23.01 = b
