Answer:
(D) 7
Step-by-step explanation:
It is given that NELR is a parallelogram, then using the property of parallelogram, we have
[tex]{\angle}N+{\angle}E=180{\circ}[/tex] (Sum of Corresponding angles of parallelogram is 180°)
[tex]7x+33+11x+21=180^{\circ}[/tex]
⇒[tex]18x+54=180[/tex]
⇒[tex]18x=126[/tex]
⇒[tex]x=7[/tex]
Therefore, the value of x will be 7.
Hence, option (D) is correct.
