Two vertical angles are complementary. Find the number of degrees in each angle.

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.
