In the triangle ABC, solve the triangle according to the following conditions, two of which are A a=7,b=2,c=8 B a = 10, B = 45 degrees, C = 75 degrees\ C a = 7, B = 5, a = 80 degrees D a = 7, B = 8, a = 45 degrees

From Sina / a = SINB / B, the angle B is 53 degrees or 127 degrees. The big side is opposite to the big angle, so both values of angle B can be taken
