What is the supplementary angle of 161 degrees? Here we will define the supplementary angle of 161 degrees, show you how to calculate the supplementary angle of 161 degrees, and even illustrate the supplementary angle of 161 degrees (161°) so you have a solid understanding of what it means.
The supplementary angle of 161 degrees, also known as the supplement angle of 161 degrees, is the angle that when added to 161 results in a sum of 180. Therefore, to calculate the supplement angle of 161 degrees, we subtract 161 from 180. Here is the formula, the math, and the answer:
180 - angle = supplement angle
180 - 161 = 19
19 degrees
161 degrees plus the supplementary angle of 161 degrees equals 180 degrees, which means that together they will make a straight line.
The illustration below shows 161 degrees colored in red and the supplementary angle of 161 degrees, which is 19 degrees, colored in green.
As you can see from the illustration above, 161 degrees and 19 degrees form a straight line together. This proves that the two angles, 161 degrees and 19 degrees, are supplementary angles.
