The value of x is 7 because in a parallelogram the diagonals bisect each other option (D) 7 is correct.
What is parallelogram?
In two-dimensional geometry, it is a plane shape having four sides, in which two pairs of sides are parallel to each other and equal in length. The sum of all angles in a parallelogram is 360°.
We have:
Parallelogram ABCD
We know,
In parallelogram the diagonals bisect each other:
So,
AE = AC/2
3x - 7 = 28/2
3x - 7 = 14
3x = 21
x = 7
Thus, the value of x is 7 because in a parallelogram the diagonals bisect each other option (D) 7 is correct.
