What is the supplementary angle of 159 degrees? Here we will define the supplementary angle of 159 degrees, show you how to calculate the supplementary angle of 159 degrees, and even illustrate the supplementary angle of 159 degrees (159°) so you have a solid understanding of what it means.
The supplementary angle of 159 degrees, also known as the supplement angle of 159 degrees, is the angle that when added to 159 results in a sum of 180. Therefore, to calculate the supplement angle of 159 degrees, we subtract 159 from 180. Here is the formula, the math, and the answer:
180 - angle = supplement angle
180 - 159 = 21
21 degrees
159 degrees plus the supplementary angle of 159 degrees equals 180 degrees, which means that together they will make a straight line.
The illustration below shows 159 degrees colored in red and the supplementary angle of 159 degrees, which is 21 degrees, colored in green.
As you can see from the illustration above, 159 degrees and 21 degrees form a straight line together. This proves that the two angles, 159 degrees and 21 degrees, are supplementary angles.
