Question
How i can solve 4 unknown variable in 4 non linear equations involving complex numbers?

The equations are :

cos(theta)+i*sin(theta)*a= 0.7099
i*b*sin(theta)-sin(theta)*c =0.1277-0.6926*i
i*b*sin(theta)+sin(theta)*c =0.1277+0.6926*i

cos(theta)-i*sin(theta)*a=-0.7099

I want the solution please by hand as well as by matlab.
