Question

Point B is on line segment AC. Given BC=9 and AB=11, determine the length AC.

Answer 1

`AC=20`

Explanation:

The line segment AC is the entire length of the line. Within this segment, point B is found.

Point B, in a way, splits the segment into two, creating the segments AB and BC.

To find the length of AC, add the lengths of the lines AB and BC together:

`AB=11\\BC=9\\AB+BC=AC\\11+9=AC\\20=AC`

The length of AC is 20.

:Done

Answer 2

20 units.

Explanation:

Segment AC is broken into two parts by point B. That means that the length of segment AB plus the length of segment BC equals the length of segment AC.

If BC = 9, and AB = 11, AC = 9 + 11 = 20 units.

Hope this helps!
