find the value of x for which WXYZ must be a parallelogram.

Answer:
(D)[tex]x=2[/tex]
Step-by-step explanation:
It is given that ∠Z≅∠X, m∠W=4x+20 and m∠Y=x+2.
Now, we know that to make WXYZ a parallelogram, using the property that the opposite angles of the parallelogram are equal in measure, therefore
[tex]m{\angle}W=m{\angle}Y[/tex]
Substituting the given values, we have
[tex]4x+20=x+26[/tex]
⇒[tex]4x-x=26-20[/tex]
⇒[tex]3x=6[/tex]
⇒[tex]x=2[/tex]
Thus, for the value of x=2, WXYZ must be a parallelogram.
Hence, option (D) is correct.
