Hi, I'm happy to help!

First, we need to find BC. We know, because B is the midpoint of AC, that AB and BC are congruent, or the same length. We are told that AB is 3.

<u>So, BC is 3 also.</u>

Next, we need to find AC. AC is a combination of AB and BC, so, we just add them.

3+3=6

<u>AC is 6.</u>

Finally, we need to find DE. We know that AC and CE are congruent because of this sign: ≅. This means they are the same length. We can then know that CE is 6 also. To find DE we need to take the length of CD away from CE. We know that CD is 2, so now, we subtract.]

6-2=4

<u>DE is 4.</u>

<u></u>

I hope this was helpful, keep learning! :D
