The figure is not marked in any way that would indicate it is a parallelogram. If we assume it is, then
... BE = DE
... 10x -3 = 8x -1 . . substitute the given expressions
... 2x = 2 . . . . . . . . add 3-8x
... x = 1 . . . . . . . . . . divide by 2
The appropriate choice is ...
... A. 1 unit
_____
Since the figure is not marked to indicate BE=DE, you could argue that any answer is correct.
