Answer:
Option C is your answer ( x = 6 and y = 3)
Explanation:
For a parallelogram opposites are parallel and are equal so we use this information to calculate the value of x and y so here goes,
For x :
Lets take the sides AB and DC both are parallel and since it's a parallelogram they must be equal so we equate both the sides like this ,
we found the value of x = 6 now we need the value of y
For y :
We take the sides AD and BC since they are parallel and opposites are equal so ,
so now the value of y = 3 so Option C is your answer
