The image isn't uploading properly, but it's a triangle in which side AB = 13 degrees, side BC = 20 degrees, and side AC = 21 degrees. They want me to find sin(*C*). I've figured out that *C* is 36.87 degrees (and B is 75.75 degrees), but I have no idea how to find sin(*C*) going from here.

Thanks in advance!
