What is the supplementary angle of 16.3 degrees? Here we will define the supplementary angle of 16.3 degrees, show you how to calculate the supplementary angle of 16.3 degrees, and even illustrate the supplementary angle of 16.3 degrees (16.3°) so you have a solid understanding of what it means.
The supplementary angle of 16.3 degrees, also known as the supplement angle of 16.3 degrees, is the angle that when added to 16.3 results in a sum of 180. Therefore, to calculate the supplement angle of 16.3 degrees, we subtract 16.3 from 180. Here is the formula, the math, and the answer:
180 - angle = supplement angle
180 - 16.3 = 163.7
163.7 degrees
16.3 degrees plus the supplementary angle of 16.3 degrees equals 180 degrees, which means that together they will make a straight line.
The illustration below shows 16.3 degrees colored in red and the supplementary angle of 16.3 degrees, which is 163.7 degrees, colored in green.

As you can see from the illustration above, 16.3 degrees and 163.7 degrees form a straight line together. This proves that the two angles, 16.3 degrees and 163.7 degrees, are supplementary angles.
