value of x = 2

Step-by-step explanation:

the given quadrilateral will be a parallelogram if their diagonals bisects each other so,

if 5x - 1 = 2x + 5 , then the given quadrilateral is a parallelogram.

now,

=》 5x - 1 = 2x + 5

=》 5x - 2x = 5 + 1

=》3x = 6

=》x = 6 ÷ 3

=》x = 2

hence, if x = 2 units, then the given figure will be a parallelogram.
