Question

25 points and brainliest if done completely
In the following diagram, points C, A, and B are collinear.

Use complete sentences to describe the sum of CA and AB.

Answer 1

The sum of CA and AB is simply CB.

If the length of CA=5 and the length of AB=6, the sum of CB is the total length which is 11.

This is true because the problem states that the points are all "co-linear" meaning that all the points lie on the same line.
