What is the supplementary angle of 113.1 degrees? Here we will define the supplementary angle of 113.1 degrees, show you how to calculate the supplementary angle of 113.1 degrees, and even illustrate the supplementary angle of 113.1 degrees (113.1°) so you have a solid understanding of what it means.
The supplementary angle of 113.1 degrees, also known as the supplement angle of 113.1 degrees, is the angle that when added to 113.1 results in a sum of 180. Therefore, to calculate the supplement angle of 113.1 degrees, we subtract 113.1 from 180. Here is the formula, the math, and the answer:
180 - angle = supplement angle
180 - 113.1 = 66.9
66.9 degrees
113.1 degrees plus the supplementary angle of 113.1 degrees equals 180 degrees, which means that together they will make a straight line.
The illustration below shows 113.1 degrees colored in red and the supplementary angle of 113.1 degrees, which is 66.9 degrees, colored in green.
As you can see from the illustration above, 113.1 degrees and 66.9 degrees form a straight line together. This proves that the two angles, 113.1 degrees and 66.9 degrees, are supplementary angles.
