Answer:

A

Step-by-step explanation:

Diagonals of a parallelogram bisect each other.

3x = 3

x = 1

y = x

y = 1

In a parallelogram, the parts in which each diagonal cuts the other are congruent.

This means that we must have

[tex]\begin{cases}3=3x\\x=y\end{cases}[/tex]

From the first equation we can deduce x=1, and thus y=x=1.
