What is the supplementary angle of 125 degrees? Here we will define the supplementary angle of 125 degrees, show you how to calculate the supplementary angle of 125 degrees, and even illustrate the supplementary angle of 125 degrees (125°) so you have a solid understanding of what it means.
The supplementary angle of 125 degrees, also known as the supplement angle of 125 degrees, is the angle that when added to 125 results in a sum of 180. Therefore, to calculate the supplement angle of 125 degrees, we subtract 125 from 180. Here is the formula, the math, and the answer:
180 - angle = supplement angle
180 - 125 = 55
55 degrees
125 degrees plus the supplementary angle of 125 degrees equals 180 degrees, which means that together they will make a straight line.
The illustration below shows 125 degrees colored in red and the supplementary angle of 125 degrees, which is 55 degrees, colored in green.
As you can see from the illustration above, 125 degrees and 55 degrees form a straight line together. This proves that the two angles, 125 degrees and 55 degrees, are supplementary angles.
