What is the supplementary angle of 142 degrees? Here we will define the supplementary angle of 142 degrees, show you how to calculate the supplementary angle of 142 degrees, and even illustrate the supplementary angle of 142 degrees (142°) so you have a solid understanding of what it means.
The supplementary angle of 142 degrees, also known as the supplement angle of 142 degrees, is the angle that when added to 142 results in a sum of 180. Therefore, to calculate the supplement angle of 142 degrees, we subtract 142 from 180. Here is the formula, the math, and the answer:
180 - angle = supplement angle
180 - 142 = 38
38 degrees
142 degrees plus the supplementary angle of 142 degrees equals 180 degrees, which means that together they will make a straight line.
The illustration below shows 142 degrees colored in red and the supplementary angle of 142 degrees, which is 38 degrees, colored in green.
As you can see from the illustration above, 142 degrees and 38 degrees form a straight line together. This proves that the two angles, 142 degrees and 38 degrees, are supplementary angles.
