What is the supplementary angle of 131.2 degrees? Here we will define the supplementary angle of 131.2 degrees, show you how to calculate the supplementary angle of 131.2 degrees, and even illustrate the supplementary angle of 131.2 degrees (131.2°) so you have a solid understanding of what it means.
The supplementary angle of 131.2 degrees, also known as the supplement angle of 131.2 degrees, is the angle that when added to 131.2 results in a sum of 180. Therefore, to calculate the supplement angle of 131.2 degrees, we subtract 131.2 from 180. Here is the formula, the math, and the answer:
180 - angle = supplement angle
180 - 131.2 = 48.8
48.8 degrees
131.2 degrees plus the supplementary angle of 131.2 degrees equals 180 degrees, which means that together they will make a straight line.
The illustration below shows 131.2 degrees colored in red and the supplementary angle of 131.2 degrees, which is 48.8 degrees, colored in green.
As you can see from the illustration above, 131.2 degrees and 48.8 degrees form a straight line together. This proves that the two angles, 131.2 degrees and 48.8 degrees, are supplementary angles.
