B2 = 180 - B1
B2 = 180 - 55.6 = 124.4
C2 = 180 - 124.4 - 45 = 10.6
c = 6
c = 1.56

17. This is called the Ambiguous Case. This
means that the information isn't perfectly
clear. The information leads to more than
1 possible solution.
Which is correct? Since there isn't any
more information given in the question to
help us determine which is the correct
triangle we say both are correct, since
both are possible.
