45/4

Step-by-step explanation:

XY= 11.25

Step-by-step explanation:

So if the shapes are similar than the dimensions are similar also. So check it right we know that 12 doesn't go into 27 but we can still divide to solve for the dimension. so 27/12 = 2.25. We can also check this answer by multiplying 8 by 2.25 to hopefully get 18 since side AC is similar to side XZ. Since our numbers check out we can mulitply 5*2.25 to get 11.25 as the side for XY
