Answer:
BC = 3
AC = 6
DE = 4
Step-by-step explanation:
Given that B is the midpoint of AC, this means that AB and BC are equal.
Since AB = 3, BC = 3
AC = AB + BC
= 3 + 3
AC = 6
AC is equivalent to CE
Since AC = 6
CE = 6
But CE = CD + DE
Given CD = 2
CE = 2 + DE
6 = 2 + DE
Subtract 2 from both sides
6 - 2 = 2 + DE - 2
DE = 4
