Question

The measure of an angle is 111°. What is the measure of a supplementary angle?

Answer 1

The measure of a supplementary angle to 111° is found by subtracting 111° from 180°. The measure of the supplementary angle is 69°.

Step-by-step explanation:

The measure of a supplementary angle to 111° is found by subtracting the given angle from 180°, because the definition of supplementary angles is that the sum of the angles is 180°. Therefore:

1. Start with the full measure of a straight angle, which is 180°.
2. Subtract the given angle from 180°: 180° - 111° = 69°.

The measure of the supplementary angle is 69°.

Answer 2

Supplementary is 180 degrees
