Answer:
D. 15 in.
Step-by-step explanation:
KL = 4 in.
ML = 6 in.
XY = 10 in.
You can create a proportion by doing 10/4 = 5/2 = 2.5.
Then, multiply it by the value of ML (6 in) by the proportion 2.5 to get the value of ZY (15 in) since both trapezoids are porportional/similar figures.
Hope this helps!
