Answer: Angle a = 47.7 degrees, b = 81.0 degrees, and c = 54.3 degrees
Step-by-step explanation: Since this triangle represents an SSS case(meaning that all sides of the triangle are given), we can use the law of cosines equation and plug the values in for all the sides to get the angles, thus solving the triangle. The equation is below.

Once I found angle A by solving and using arccos function, I used the law of sines,

and got the angles for the other sides.
