Answer:
We can find the value of XY
Explanation:
ABCD is similar to WXYZ
we know both the perimeters so lets assume they are:
ABCD=60
WXYZ=80
From the perimeters we can find the ratio of the two polygons
60/80= 3/4
since BC is similar to XY then
BC/XY = 30/XY = 3/4
cross multiplying will give us XY= 40
