What is the supplementary angle of 38.5 degrees? Here we will define the supplementary angle of 38.5 degrees, show you how to calculate the supplementary angle of 38.5 degrees, and even illustrate the supplementary angle of 38.5 degrees (38.5°) so you have a solid understanding of what it means.
The supplementary angle of 38.5 degrees, also known as the supplement angle of 38.5 degrees, is the angle that when added to 38.5 results in a sum of 180. Therefore, to calculate the supplement angle of 38.5 degrees, we subtract 38.5 from 180. Here is the formula, the math, and the answer:
180 - angle = supplement angle
180 - 38.5 = 141.5
141.5 degrees
38.5 degrees plus the supplementary angle of 38.5 degrees equals 180 degrees, which means that together they will make a straight line.
The illustration below shows 38.5 degrees colored in red and the supplementary angle of 38.5 degrees, which is 141.5 degrees, colored in green.
As you can see from the illustration above, 38.5 degrees and 141.5 degrees form a straight line together. This proves that the two angles, 38.5 degrees and 141.5 degrees, are supplementary angles.
