What is the supplementary angle of 131 degrees? Here we will define the supplementary angle of 131 degrees, show you how to calculate the supplementary angle of 131 degrees, and even illustrate the supplementary angle of 131 degrees (131°) so you have a solid understanding of what it means.
The supplementary angle of 131 degrees, also known as the supplement angle of 131 degrees, is the angle that when added to 131 results in a sum of 180. Therefore, to calculate the supplement angle of 131 degrees, we subtract 131 from 180. Here is the formula, the math, and the answer:
180 - angle = supplement angle
180 - 131 = 49
49 degrees
131 degrees plus the supplementary angle of 131 degrees equals 180 degrees, which means that together they will make a straight line.
The illustration below shows 131 degrees colored in red and the supplementary angle of 131 degrees, which is 49 degrees, colored in green.
As you can see from the illustration above, 131 degrees and 49 degrees form a straight line together. This proves that the two angles, 131 degrees and 49 degrees, are supplementary angles.
