What is the supplementary angle of 118 degrees? Here we will define the supplementary angle of 118 degrees, show you how to calculate the supplementary angle of 118 degrees, and even illustrate the supplementary angle of 118 degrees (118°) so you have a solid understanding of what it means.
The supplementary angle of 118 degrees, also known as the supplement angle of 118 degrees, is the angle that when added to 118 results in a sum of 180. Therefore, to calculate the supplement angle of 118 degrees, we subtract 118 from 180. Here is the formula, the math, and the answer:
180 - angle = supplement angle
180 - 118 = 62
62 degrees
118 degrees plus the supplementary angle of 118 degrees equals 180 degrees, which means that together they will make a straight line.
The illustration below shows 118 degrees colored in red and the supplementary angle of 118 degrees, which is 62 degrees, colored in green.
As you can see from the illustration above, 118 degrees and 62 degrees form a straight line together. This proves that the two angles, 118 degrees and 62 degrees, are supplementary angles.
