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