What is the supplementary angle of 126 degrees? Here we will define the supplementary angle of 126 degrees, show you how to calculate the supplementary angle of 126 degrees, and even illustrate the supplementary angle of 126 degrees (126°) so you have a solid understanding of what it means.
The supplementary angle of 126 degrees, also known as the supplement angle of 126 degrees, is the angle that when added to 126 results in a sum of 180. Therefore, to calculate the supplement angle of 126 degrees, we subtract 126 from 180. Here is the formula, the math, and the answer:
180 - angle = supplement angle
180 - 126 = 54
54 degrees
126 degrees plus the supplementary angle of 126 degrees equals 180 degrees, which means that together they will make a straight line.
The illustration below shows 126 degrees colored in red and the supplementary angle of 126 degrees, which is 54 degrees, colored in green.
As you can see from the illustration above, 126 degrees and 54 degrees form a straight line together. This proves that the two angles, 126 degrees and 54 degrees, are supplementary angles.
