What is the supplementary angle of 23.9 degrees? Here we will define the supplementary angle of 23.9 degrees, show you how to calculate the supplementary angle of 23.9 degrees, and even illustrate the supplementary angle of 23.9 degrees (23.9°) so you have a solid understanding of what it means.
The supplementary angle of 23.9 degrees, also known as the supplement angle of 23.9 degrees, is the angle that when added to 23.9 results in a sum of 180. Therefore, to calculate the supplement angle of 23.9 degrees, we subtract 23.9 from 180. Here is the formula, the math, and the answer:
180 - angle = supplement angle
180 - 23.9 = 156.1
156.1 degrees
23.9 degrees plus the supplementary angle of 23.9 degrees equals 180 degrees, which means that together they will make a straight line.
The illustration below shows 23.9 degrees colored in red and the supplementary angle of 23.9 degrees, which is 156.1 degrees, colored in green.
As you can see from the illustration above, 23.9 degrees and 156.1 degrees form a straight line together. This proves that the two angles, 23.9 degrees and 156.1 degrees, are supplementary angles.
