Question

1. if segment ac equals 12 and segment bc equals 5, what is the total length of segment ab?

2
7
17
60

Explanation:

Step1: Identify segment relationship

We know that $AB=AC - BC$ (assuming point B lies on segment AC). Here $AC = 12$ and $BC=5$.
$AB=AC - BC=12 - 5$

Step2: Calculate length of AB

$12-5 = 7$

Answer:

B. 7
