Therefore, our final simplification is

Answer:
1st and 2nd statements are true.
Step-by-step explanation:
We are asked to choose the correct statements that can prove that quadrilateral DEFG is a parallelogram.
We will use parallelogram properties to answer this problem.
Since we know that a parallelogram has two sets of opposite angles congruent, therefore, 1st option is a correct choice.
Since a parallelogram has one set of opposite sides that are both congruent and parallel, therefore, second statement is true.
Since the consecutive angles of a parallelogram are supplementary, therefore, 3rd statement is not true.
Since the diagonals of parallelogram bisect each other, therefore, 4th statement is not true.
Answer:
x = 27
Step-by-step explanation:
mean is calculated as
mean = 
sum = 2 + 7 + x = 9 + x and count = 3 , then
= 12 ( multiply both sides by 3 to clear the fraction )
9 + x = 36 ( subtract 9 from both sides )
x = 27
