B = 44 degrees
a = 23
b = 12
use law of sines to solve for angle A:
b/sinB = a/sinA
12/sin44 = 23/sinA
12sinA = 23sin44
sinA = (23sin44)/12
sinA = 1.3314
since sinx is only defined for values between -1 and 1 it is impossible to form a triangle with given the dimensions. hence no possible solutions
