Answer:
The length of AC is 10 units.
Step-by-step explanation:
We are given a segment AB that is 20 units long. C is the midpoint on this segment, so we can represent this segment as ACB, where C is the midpoint. Midpoint just generally means the middle, so point C bisects this segment. We are asked the length of AC which would be half of the segment. Therefore, to find the length of AC we would divide the length of AB by 2 (or multiply it by a half, same thing). When we do this, we get the length of AC which is 10 units.
