Which Triangle has 2 solutions?

a. A=130 degrees, a=19, b=11
b. A=45 degrees, a= 4(sqrt 2) b=8
c. A=32 degrees, a=16, b= 21
d. A=90 degrees, a=25, b=15

I really don't know how to do this one so I can't put what my answer is.

  1. You'll have to use the Ambiguous Case for the Law of Sines.

    I would give you a few links to some good websites. However, I'm not allowed. Try googling "ambiguous case law sines" without the quotes for some relevant information.
