How do you solve and how many solutions does the triangle have if you are given angle C = 115 degrees, side b = 54.8, side c = 53.4?

Use the trig identity: sin A/a = sin B/b
Explanation:
sin A = 0.92 -> A = 66.92 deg, and A = 180 - 66.92 = 111.08
The result A = 111.08 is rejected because C = 115.
Angle B = 180 - A - C = 180 - 66.92 - 115 =
Angle B could not be negative, then the given data doesn't match.
Side lengths b and c are not correct.
