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