Answer:
63°
Step-by-step explanation:
Vertical angles are the same size (congruent). If you cross two lines you make 4 angles. Vertical angles are the pair that are "back-to-back" touching only at one point (NOT side-by-side, sharing a side). I like to think of a pair of scissors. When you squeeze the handle together, the blades go together. That's like vertical angles.
