B is the midpoint of line segment AC. Find the measure of line segment AC. *25427084
iris [78.8K]

Answer:

84 units

Explanation:

If B is the midpoint of line AC, then B divides AC into two equal parts (AB and BC).

Therefore:

AB=BC

2x-8=x+17

2x-x=17+8

x=25

Therefore, the measure of the line segment AC

=2(2x-8)

=2(2(25)-8)

=2(50-8)

=2(42)

AC=84 units
