Answer:
x = 1
Explanation:
See the attached figure.
Here, the parallelogram P was dilated to form parallelogram P'.
Therefore, P and P' will be similar to each other.
So, the corresponding sides of parallelogram P and parallelogram P' will be in the same ratio.
Then,
⇒ 2(x + 3) = 8
⇒ 2x + 6 = 8
⇒ 2x = 2
⇒ x = 1 (Answer)
