Answer: The value of x must be 7 units.
Step-by-step explanation:
Since we have given that
ABCD is a parallelogram.
Suppose that AC and BD intersect at o.
So, AO = OC.
And we have given that
AO = 5x
OC = 6x-7
According to question,
[tex]5x=6x-7\\\\5x-6x=-7\\\\-x=-7\\\\x=7[/tex]
Hence, the value of x must be 7 units.
