What is the supplementary angle of 74 degrees? Here we will define the supplementary angle of 74 degrees, show you how to calculate the supplementary angle of 74 degrees, and even illustrate the supplementary angle of 74 degrees (74°) so you have a solid understanding of what it means.
The supplementary angle of 74 degrees, also known as the supplement angle of 74 degrees, is the angle that when added to 74 results in a sum of 180. Therefore, to calculate the supplement angle of 74 degrees, we subtract 74 from 180. Here is the formula, the math, and the answer:
180 - angle = supplement angle
180 - 74 = 106
106 degrees
74 degrees plus the supplementary angle of 74 degrees equals 180 degrees, which means that together they will make a straight line.
The illustration below shows 74 degrees colored in red and the supplementary angle of 74 degrees, which is 106 degrees, colored in green.
As you can see from the illustration above, 74 degrees and 106 degrees form a straight line together. This proves that the two angles, 74 degrees and 106 degrees, are supplementary angles.
