They cannot be determined.

Answer 1

To determine the angle measures of a triangle, we can use the law of cosines and the law of sines. However, in this case, we are not given any angles or the length of the angle's opposite side, so we cannot determine the angle measures of the triangle. Therefore, the correct answer is: They cannot be determined.
