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!

sides are not measured in degrees. 

Angles are measured in degrees and you need three letters to define an angle
