What is the supplementary angle of 164.2 degrees? Here we will define the supplementary angle of 164.2 degrees, show you how to calculate the supplementary angle of 164.2 degrees, and even illustrate the supplementary angle of 164.2 degrees (164.2°) so you have a solid understanding of what it means.
The supplementary angle of 164.2 degrees, also known as the supplement angle of 164.2 degrees, is the angle that when added to 164.2 results in a sum of 180. Therefore, to calculate the supplement angle of 164.2 degrees, we subtract 164.2 from 180. Here is the formula, the math, and the answer:
180 - angle = supplement angle
180 - 164.2 = 15.8
15.8 degrees
164.2 degrees plus the supplementary angle of 164.2 degrees equals 180 degrees, which means that together they will make a straight line.
The illustration below shows 164.2 degrees colored in red and the supplementary angle of 164.2 degrees, which is 15.8 degrees, colored in green.
As you can see from the illustration above, 164.2 degrees and 15.8 degrees form a straight line together. This proves that the two angles, 164.2 degrees and 15.8 degrees, are supplementary angles.
