What is the supplementary angle of 103 degrees? Here we will define the supplementary angle of 103 degrees, show you how to calculate the supplementary angle of 103 degrees, and even illustrate the supplementary angle of 103 degrees (103°) so you have a solid understanding of what it means.
The supplementary angle of 103 degrees, also known as the supplement angle of 103 degrees, is the angle that when added to 103 results in a sum of 180. Therefore, to calculate the supplement angle of 103 degrees, we subtract 103 from 180. Here is the formula, the math, and the answer:
180 - angle = supplement angle
180 - 103 = 77
77 degrees
103 degrees plus the supplementary angle of 103 degrees equals 180 degrees, which means that together they will make a straight line.
The illustration below shows 103 degrees colored in red and the supplementary angle of 103 degrees, which is 77 degrees, colored in green.
As you can see from the illustration above, 103 degrees and 77 degrees form a straight line together. This proves that the two angles, 103 degrees and 77 degrees, are supplementary angles.
