What is the supplementary angle of 100 degrees? Here we will define the supplementary angle of 100 degrees, show you how to calculate the supplementary angle of 100 degrees, and even illustrate the supplementary angle of 100 degrees (100°) so you have a solid understanding of what it means.
The supplementary angle of 100 degrees, also known as the supplement angle of 100 degrees, is the angle that when added to 100 results in a sum of 180. Therefore, to calculate the supplement angle of 100 degrees, we subtract 100 from 180. Here is the formula, the math, and the answer:
180 - angle = supplement angle
180 - 100 = 80
80 degrees
100 degrees plus the supplementary angle of 100 degrees equals 180 degrees, which means that together they will make a straight line.
The illustration below shows 100 degrees colored in red and the supplementary angle of 100 degrees, which is 80 degrees, colored in green.
As you can see from the illustration above, 100 degrees and 80 degrees form a straight line together. This proves that the two angles, 100 degrees and 80 degrees, are supplementary angles.
