Answer:

XY = 18

Explanation:

In this picture, XD = DW, and YE = EZ, so we are able to use the midline theorem. From the midline theorem, we can easily determine that (XY + WZ)/2 = DE. From this, we can plug in: (XY +
(4)/(3)XY) = 2 * 21. So, simplifying that equation gets:
(7)/(3)XY = 42. So, XY =
42 * (3)/(7) = 18.

(if i'm going to be honest, i'm sure your geometry teacher covered this in class. just make sure to pay attention next time.)
