What is the supplementary angle of 53 degrees? Here we will define the supplementary angle of 53 degrees, show you how to calculate the supplementary angle of 53 degrees, and even illustrate the supplementary angle of 53 degrees (53°) so you have a solid understanding of what it means.
The supplementary angle of 53 degrees, also known as the supplement angle of 53 degrees, is the angle that when added to 53 results in a sum of 180. Therefore, to calculate the supplement angle of 53 degrees, we subtract 53 from 180. Here is the formula, the math, and the answer:
180 - angle = supplement angle
180 - 53 = 127
127 degrees
53 degrees plus the supplementary angle of 53 degrees equals 180 degrees, which means that together they will make a straight line.
The illustration below shows 53 degrees colored in red and the supplementary angle of 53 degrees, which is 127 degrees, colored in green.

As you can see from the illustration above, 53 degrees and 127 degrees form a straight line together. This proves that the two angles, 53 degrees and 127 degrees, are supplementary angles.
