Answer:
Side XY is 6 units
Explanation:
The order of ∆ QRS will be the same as the order of ∆ XYZ and the corresponding order between the 2 are congruent.
Angle Q is congruent to angle X because they are listed first. Angle R is congruent to angle Y because they are listed second. Angle S is congruent to angle Z because they are listed third.
We can see that side QR is 6 units. The corresponding side on triangle XYZ is side XY.
