What is the supplementary angle of 45.5 degrees? Here we will define the supplementary angle of 45.5 degrees, show you how to calculate the supplementary angle of 45.5 degrees, and even illustrate the supplementary angle of 45.5 degrees (45.5°) so you have a solid understanding of what it means.
The supplementary angle of 45.5 degrees, also known as the supplement angle of 45.5 degrees, is the angle that when added to 45.5 results in a sum of 180. Therefore, to calculate the supplement angle of 45.5 degrees, we subtract 45.5 from 180. Here is the formula, the math, and the answer:
180 - angle = supplement angle
180 - 45.5 = 134.5
134.5 degrees
45.5 degrees plus the supplementary angle of 45.5 degrees equals 180 degrees, which means that together they will make a straight line.
The illustration below shows 45.5 degrees colored in red and the supplementary angle of 45.5 degrees, which is 134.5 degrees, colored in green.
As you can see from the illustration above, 45.5 degrees and 134.5 degrees form a straight line together. This proves that the two angles, 45.5 degrees and 134.5 degrees, are supplementary angles.
