Answer:

Option A

1

Step-by-step explanation:

7x + 7 = 18 - 4x. [Alternate interior angle]

=> 7x + 4x = 18 - 7

=> 11x = 11

[tex] = > x = \frac{11}{11} [/tex]

=> x = 1 (Ans)
x=1

One of the properties of a parallelogram is that the diagonals bisect each other at their midpoints, so:
7x+7=18-4x
11x=11
x=1
