I got this problem wrong on a test and i want to know how to fix it. In triangle ABC, angle A is 20 degrees and side AC is 7.89 units, find the other sides and angles

As it stands, there are only 2 pieces of information, which is insufficient.
Is it a rightangled triangle?
If so, where is the rightangle?
