What is the supplementary angle of 108.8 degrees? Here we will define the supplementary angle of 108.8 degrees, show you how to calculate the supplementary angle of 108.8 degrees, and even illustrate the supplementary angle of 108.8 degrees (108.8°) so you have a solid understanding of what it means.
The supplementary angle of 108.8 degrees, also known as the supplement angle of 108.8 degrees, is the angle that when added to 108.8 results in a sum of 180. Therefore, to calculate the supplement angle of 108.8 degrees, we subtract 108.8 from 180. Here is the formula, the math, and the answer:
180 - angle = supplement angle
180 - 108.8 = 71.2
71.2 degrees
108.8 degrees plus the supplementary angle of 108.8 degrees equals 180 degrees, which means that together they will make a straight line.
The illustration below shows 108.8 degrees colored in red and the supplementary angle of 108.8 degrees, which is 71.2 degrees, colored in green.
As you can see from the illustration above, 108.8 degrees and 71.2 degrees form a straight line together. This proves that the two angles, 108.8 degrees and 71.2 degrees, are supplementary angles.
