What are the Properties of the Sides of a Parallelogram?
The two opposite sides of a parallelogram are parallel to each other and are also of equal lengths.
Thus:
AD = BC
Substitute
5x + 3 = 38
5x = 38 - 3
5x = 35
x = 7
Therefore, considering the properties of the sides of a parallelogram, the value of x is: B. 7.
