What is the supplementary angle of 72.3 degrees? Here we will define the supplementary angle of 72.3 degrees, show you how to calculate the supplementary angle of 72.3 degrees, and even illustrate the supplementary angle of 72.3 degrees (72.3°) so you have a solid understanding of what it means.
The supplementary angle of 72.3 degrees, also known as the supplement angle of 72.3 degrees, is the angle that when added to 72.3 results in a sum of 180. Therefore, to calculate the supplement angle of 72.3 degrees, we subtract 72.3 from 180. Here is the formula, the math, and the answer:
180 - angle = supplement angle
180 - 72.3 = 107.7
107.7 degrees
72.3 degrees plus the supplementary angle of 72.3 degrees equals 180 degrees, which means that together they will make a straight line.
The illustration below shows 72.3 degrees colored in red and the supplementary angle of 72.3 degrees, which is 107.7 degrees, colored in green.
As you can see from the illustration above, 72.3 degrees and 107.7 degrees form a straight line together. This proves that the two angles, 72.3 degrees and 107.7 degrees, are supplementary angles.
