Find the value of x.

Answer:
A. 7
Step-by-step explanation:
The problem is poorly specified, so <em>technically cannot be answered with a specific number</em>.
If we assume the "horizontal" lines are all parallel, then the one marked 21-x has a length that is the average of the other two:
(17 +11)/2 = 21 -x
14 = 21 -x
x = 21 -14 = 7
The value of x is 7.
