So im told to find the value of each variable. It's a X. One side equals 3xº and the other side says (80-x)º

3x=80-x
4x=80
x=20 As you can see the value I got was 20. But in another question it tells me to find the measure of the labeled angles. How do I do that?

There is no way for us to know what diagram you are looking at.

Your statement of "One side equals 3x° and the other side says (80-x)° " makes no sense
Sides are not measured in degrees, angles are .

The equation is solved correctly, assuming the equation is valid.
Its a big gigantic X . That's the diagram. Its a vertical angle
