Question

Point C is midpoint of AB for A(1-2) and B(7,2). What is the length of segment AC? Round to the nearest tenth.

Answer 1

First, we are going to calculate the length of the segment AB

$l=\sqrt[]{(1-7)^2+(-2-2)^2}=\sqrt[]{(-6)^2+(-4)^2}=\sqrt[]{36+16}=7.2$

Point C is the midpoint so the length of the segment AC will be half of the length AB

the length of the segment AC is 7.2/2 =3.6
