Urgent Trig Help law of sines

**Hi!**

I am learning the Law of Sines, and have no idea what to do. I have notes from my class, but the whole multiple solutions thing is throwing me. I do, however, understand the basics about the law of Sines.

Here is a problem I don't understand- it is an Ambiguous case:

Determine the number of possible solutions. If a solution exists, solve the triangle.

Triangle ABC

C=17 degrees a= 10 units c= 11 units

How would I go about finding <A and side B so that I can check to see how many solutions?

Thanks,

Lyrixa
