Question

1. if ab = 8 and bc = 5, what is ac?

12
15
13
3

Explanation:

Step1: Assume points are collinear

If points A, B, and C are collinear and B is between A and C, then by the segment - addition postulate, \(AC=AB + BC\).

Step2: Substitute given values

Given \(AB = 8\) and \(BC = 5\), so \(AC=8 + 5\).

Step3: Calculate the result

\(8+5 = 13\).

Answer:

C. 13
