Answer
D. WY = 12, m angle XWZ = 51°
Explanation:
since WX is 6 and XY is congruent to WX they are both 6 so add them together and you get 12 for WY
6+6=12
because we need to find the missing angle we know that we have 2 other angles, 39°, and our right angle that is 90° so we subtract both of these angles from 180
180-90-39=51°
Hope this helped
