What is the supplementary angle of 66.2 degrees? Here we will define the supplementary angle of 66.2 degrees, show you how to calculate the supplementary angle of 66.2 degrees, and even illustrate the supplementary angle of 66.2 degrees (66.2°) so you have a solid understanding of what it means.
The supplementary angle of 66.2 degrees, also known as the supplement angle of 66.2 degrees, is the angle that when added to 66.2 results in a sum of 180. Therefore, to calculate the supplement angle of 66.2 degrees, we subtract 66.2 from 180. Here is the formula, the math, and the answer:
180 - angle = supplement angle
180 - 66.2 = 113.8
113.8 degrees
66.2 degrees plus the supplementary angle of 66.2 degrees equals 180 degrees, which means that together they will make a straight line.
The illustration below shows 66.2 degrees colored in red and the supplementary angle of 66.2 degrees, which is 113.8 degrees, colored in green.
As you can see from the illustration above, 66.2 degrees and 113.8 degrees form a straight line together. This proves that the two angles, 66.2 degrees and 113.8 degrees, are supplementary angles.
