To determine the length of CE, we need to know more about the points A, B, C, D, and E, as well as their arrangement.
If we assume that the points are collinear (i.e., they lie on a straight line), and given that:
- AB = 8 units
- BC = 15 units
We can find the length of AC first:
AC = AB + BC = 8 units + 15 units = 23 units.
Without more information about the positions of points D and E, or the relationship between them and the segment AC, we cannot determine CE.
If you have any additional information or context about the arrangement of points D and E or other distances, please provide that to clarify the situation.
