What is the supplementary angle of 10.2 degrees? Here we will define the supplementary angle of 10.2 degrees, show you how to calculate the supplementary angle of 10.2 degrees, and even illustrate the supplementary angle of 10.2 degrees (10.2°) so you have a solid understanding of what it means.
The supplementary angle of 10.2 degrees, also known as the supplement angle of 10.2 degrees, is the angle that when added to 10.2 results in a sum of 180. Therefore, to calculate the supplement angle of 10.2 degrees, we subtract 10.2 from 180. Here is the formula, the math, and the answer:
180 - angle = supplement angle
180 - 10.2 = 169.8
169.8 degrees
10.2 degrees plus the supplementary angle of 10.2 degrees equals 180 degrees, which means that together they will make a straight line.
The illustration below shows 10.2 degrees colored in red and the supplementary angle of 10.2 degrees, which is 169.8 degrees, colored in green.
As you can see from the illustration above, 10.2 degrees and 169.8 degrees form a straight line together. This proves that the two angles, 10.2 degrees and 169.8 degrees, are supplementary angles.
