What is the supplementary angle of 115.1 degrees? Here we will define the supplementary angle of 115.1 degrees, show you how to calculate the supplementary angle of 115.1 degrees, and even illustrate the supplementary angle of 115.1 degrees (115.1°) so you have a solid understanding of what it means.
The supplementary angle of 115.1 degrees, also known as the supplement angle of 115.1 degrees, is the angle that when added to 115.1 results in a sum of 180. Therefore, to calculate the supplement angle of 115.1 degrees, we subtract 115.1 from 180. Here is the formula, the math, and the answer:
180 - angle = supplement angle
180 - 115.1 = 64.9
64.9 degrees
115.1 degrees plus the supplementary angle of 115.1 degrees equals 180 degrees, which means that together they will make a straight line.
The illustration below shows 115.1 degrees colored in red and the supplementary angle of 115.1 degrees, which is 64.9 degrees, colored in green.
As you can see from the illustration above, 115.1 degrees and 64.9 degrees form a straight line together. This proves that the two angles, 115.1 degrees and 64.9 degrees, are supplementary angles.
