Question

1. if point b is on line segment ac, and ab=5 units and bc=8 units, what is the length of ac?

a) 3 units
b) 40 units
c) 1.6 units
d) 13 units

a) 3 units
b) 40 units
c) 1.6 units
d) 13 units

Explanation:

Step1: Understand the segment addition

Since B is on AC, \( AC = AB + BC \).

Step2: Substitute the values

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

Step3: Calculate the sum

\( 5 + 8 = 13 \).

Answer:

D) 13 units
