7. An angle in quadrant 3 has a reference angle of 31". If the angle is greater than 600, then what is the smallest possible answer?

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.

I’m not sure what sujevtbis this

2xy/9 is the answer to this problem
