Answer:
XY is longer than ZY and ZY is longer than AB
Explanation:
The longest sides is opposite largest angle and shortest side is opposite the smallest angle.
79° is the largest angle so side XY is the longest and 36° is the smallest angle so side AB is the shortest. Side ZY is in between, longer than AB but shorter than XY
So your answer is correct
XY is longer than ZY and ZY is longer than AB
