The missing **angle** measures 103 degrees. **Complementary angles** form a right **angle** (L shape) and **have** a sum of 90 degrees. Supplementary **angles** form a straight line and **have** a sum of 180 degrees. If the relationship is given, you can subtract the given **angle** from the sum to determine the measure of the missing **angle**.

Also Know, what is the complement of an angle? Two **Angles** are Complementary when they add up to 90 degrees (a Right **Angle**). They dont have to be next to each other, just so long as the total is 90 degrees.

Similarly, it is asked, what is the complement and supplement of an angle?

The **complement** of an **angle** is what, when added to it, equals 90 degrees (90°). For example, in your problem, 90°-85°=5°. This means that the **complement** of 85° is 5°, since they add up to equal 90 degrees a right **angle**. The **supplement of an angle** is what, when added to it, equals 180 degrees.

What is the supplement of 83?

Two angles are COMPLEMENTS if the sum of their measures is 90 degrees. Two angles are **SUPPLEMENTS** if the sum of their measures is 180 degrees. The **supplement** of a 67-degree angle is a 113-degree angle because 67 113=180. The **complement** of a **83**-degree angle is a 7-degree angle because **83** 7=90.
