Question

1. if ab = 48 and bc = 22, then ac = ?

Explanation:

Step1: Identify the relationship

Since points A, B, and C are collinear and B is between A and C, we use the segment - addition postulate: $AC=AB + BC$.

Step2: Substitute the given values

Given $AB = 48$ and $BC=22$, we substitute into the formula: $AC=48 + 22$.

Step3: Calculate the sum

$48+22 = 70$.

Answer:

$70$
