What is the supplementary angle of 173 degrees? Here we will define the supplementary angle of 173 degrees, show you how to calculate the supplementary angle of 173 degrees, and even illustrate the supplementary angle of 173 degrees (173°) so you have a solid understanding of what it means.
The supplementary angle of 173 degrees, also known as the supplement angle of 173 degrees, is the angle that when added to 173 results in a sum of 180. Therefore, to calculate the supplement angle of 173 degrees, we subtract 173 from 180. Here is the formula, the math, and the answer:
180 - angle = supplement angle
180 - 173 = 7
7 degrees
173 degrees plus the supplementary angle of 173 degrees equals 180 degrees, which means that together they will make a straight line.
The illustration below shows 173 degrees colored in red and the supplementary angle of 173 degrees, which is 7 degrees, colored in green.
As you can see from the illustration above, 173 degrees and 7 degrees form a straight line together. This proves that the two angles, 173 degrees and 7 degrees, are supplementary angles.
