If two angles are vertical and are labeled with equations, what do you do to find x and the measure of each angle? (remember that would be 4 angles in a diagram) Name the steps. No need to solve. See slide 4
1. Set equations equal to find x
2. Plug x in to find the measure of the vertical angles.
3. Subtract that angle from 180 to get the other 2 angles.
