Find the value of x for which ABCD must be a parallelogram. 24 2 6 12

Answer: x = 2
Concept:
There are many properties for parallelograms, however, here, we need to focus on one property about diagonals.
Diagonals of a parallelogram bisect each other.
Solve:
<u>Given information</u>
One side of the diagonal = 6x
The other side of diagonal = 2x + 8
<u>Given expression deducted from the property of parallelogram</u>
One side = Other side
<u>Substitute values into the expression</u>
6x = 2x + 8
<u>Subtract 2x on both sides</u>
6x - 2x = 2x + 8 - 2x
4x = 8
<u>Divide 4 on both sides</u>
4x / 4 = 8 / 4
Hope this helps!! :)
