Answer:
45 degrees
Step-by-step explanation:
Vertical angles are congruent. This means the angles have the same measurement.
If two angles are complementary, they will add up to be 90.
You are wanting to solve x+x=90 then.
Combine like terms gives 2x=90.
Dividing both sides by 2 gives x=90/2.
90/2 reduced to 45.
Both of the angles are 45.
