Answer: AB = 9 units
Step-by-step explanation:
We know the length of the following segments:
AC = 22 units
BC = 13 units
Using this information, we know the total length of the line is 22 units. One part of the line is 13 units (from B to C), which means that to find the other part’s length, we subtract 13 from the total length.
22 - 13 = 9 units
