Answer:
B. 60
Step-by-step explanation:
The opposite sides of a parallelogram are parallel and congruent.
This implies that:
|UV|=|XW|
From the diagram; |UV|=15
and [tex]|XW|=\frac{1}{4}y[/tex]
We equate the two side lengths to get:
[tex]15=\frac{1}{4}y[/tex]
We multiply both sides by 4 to obtain:
[tex]4\times 15=4\times \frac{1}{4}y[/tex]
This implies that:
y=60
