Answer: The required length of AC is 22 units.
Step-by-step explanation: We are given that the point B is between the points A and C, where
[tex]AB=13.7,~~BC=8.3.[/tex]
We are to find the length of AC.
The picture of the given situation is shown in the attached figure below.
Since the point B is in between A and C, so we must have
[tex]AC=AB+BC=13.7+8.3=22.[/tex]
Thus, the required length of AC is 22 units.
