You can using the Law of Cosines.

a² = b² + c² - 2ac cosA

The posted image is too small and blurry to read reliably, but if you plug the values into the above equation you can solve for the length of the triangle's side "a" which is equivalent to side BC and is opposite angle A.

b is side AC and is opposite angle B

c is side AB is is opposite angle C
