Answer:
10
Step-by-step explanation:
The diagonals of a parallelogram bisect each other. That is, point O is the midpoint of AC. If AO = 5, then OC = 5 and AC = 5+5 = 10.
So what you do is you have to make the equation for a line with the slope of 5. Then, in the next problem, you find which one has the slope of 5 and that means that all three of those lines have the same slope so you select the one that has a slope of 5. only one needs the slope of 5 because they are all parallel so they all have the same slope. <span />
