What is the supplementary angle of 168 degrees? Here we will define the supplementary angle of 168 degrees, show you how to calculate the supplementary angle of 168 degrees, and even illustrate the supplementary angle of 168 degrees (168°) so you have a solid understanding of what it means.
The supplementary angle of 168 degrees, also known as the supplement angle of 168 degrees, is the angle that when added to 168 results in a sum of 180. Therefore, to calculate the supplement angle of 168 degrees, we subtract 168 from 180. Here is the formula, the math, and the answer:
180 - angle = supplement angle
180 - 168 = 12
12 degrees
168 degrees plus the supplementary angle of 168 degrees equals 180 degrees, which means that together they will make a straight line.
The illustration below shows 168 degrees colored in red and the supplementary angle of 168 degrees, which is 12 degrees, colored in green.
As you can see from the illustration above, 168 degrees and 12 degrees form a straight line together. This proves that the two angles, 168 degrees and 12 degrees, are supplementary angles.
