What is the supplementary angle of 71.5 degrees? Here we will define the supplementary angle of 71.5 degrees, show you how to calculate the supplementary angle of 71.5 degrees, and even illustrate the supplementary angle of 71.5 degrees (71.5°) so you have a solid understanding of what it means.
The supplementary angle of 71.5 degrees, also known as the supplement angle of 71.5 degrees, is the angle that when added to 71.5 results in a sum of 180. Therefore, to calculate the supplement angle of 71.5 degrees, we subtract 71.5 from 180. Here is the formula, the math, and the answer:
180 - angle = supplement angle
180 - 71.5 = 108.5
108.5 degrees
71.5 degrees plus the supplementary angle of 71.5 degrees equals 180 degrees, which means that together they will make a straight line.
The illustration below shows 71.5 degrees colored in red and the supplementary angle of 71.5 degrees, which is 108.5 degrees, colored in green.
As you can see from the illustration above, 71.5 degrees and 108.5 degrees form a straight line together. This proves that the two angles, 71.5 degrees and 108.5 degrees, are supplementary angles.
