Good evening Candice! The 0 deg to 540 deg stipulation in my workings applies only for angle 0.75x. We accept all angles in this range so that when we convert back to x, our angle will automatically be in the range 0 deg to 720 deg. Here the 660 deg is for x which we solved, and not 0.75x, so yes it is accepted.

There is 1 question which I think my working steps look sound but I just can't derive the model answer. I will be uploading it in a minute.
