What is the supplementary angle of 142.1 degrees? Here we will define the supplementary angle of 142.1 degrees, show you how to calculate the supplementary angle of 142.1 degrees, and even illustrate the supplementary angle of 142.1 degrees (142.1°) so you have a solid understanding of what it means.
The supplementary angle of 142.1 degrees, also known as the supplement angle of 142.1 degrees, is the angle that when added to 142.1 results in a sum of 180. Therefore, to calculate the supplement angle of 142.1 degrees, we subtract 142.1 from 180. Here is the formula, the math, and the answer:
180 - angle = supplement angle
180 - 142.1 = 37.9
37.9 degrees
142.1 degrees plus the supplementary angle of 142.1 degrees equals 180 degrees, which means that together they will make a straight line.
The illustration below shows 142.1 degrees colored in red and the supplementary angle of 142.1 degrees, which is 37.9 degrees, colored in green.
As you can see from the illustration above, 142.1 degrees and 37.9 degrees form a straight line together. This proves that the two angles, 142.1 degrees and 37.9 degrees, are supplementary angles.
