Answer:
∠CEB
Step-by-step explanation:
The vertical angle is one that is directly <em>opposite</em> to the original angle. In this image of two intersecting lines, it looks like the angle ∠CEB is directly across from our angle ∠DEA. So, the angle ∠CEB is <em>vertical to</em> ∠DEA.
Hopefully that was helpful! :)
I'll go thru the problem and then you fill in the blanks yourself.
