What to do when the unknowns x and y are inside cos & sin functions ?

I only want to get values between 0-360 degrees, not values higher than that.

My system is:

Quote:-0.84=0.3912*cos(x)+0.3824*cos(y)+0.3606*cos(225)
0=0.3912*sin(x)+0.3824*sin(y)+0.3606*sin(225)

The solution should be x=11.31º and y=302.47º
