Answer:

44.2°.

Explanation:

What is an angle?

An angle is a measure of a turn, measured in degrees or °. Angles are made up of two rays, making the sides of the angle.

What is a complementary angle?

For two angles to be complementary, they need to add up to 90°.

If we now know that two complementary angles add up to 90°, we can use this equation to solve for the missing degree:

  • 90 - 45.8 = 44.2

To check our work, we can use this equation:

  • 44.2 + 45.8 = 90

Therefore, the measure of the missing angle is 44.2°.
