What is the supplementary angle of 75 degrees? Here we will define the supplementary angle of 75 degrees, show you how to calculate the supplementary angle of 75 degrees, and even illustrate the supplementary angle of 75 degrees (75°) so you have a solid understanding of what it means.
The supplementary angle of 75 degrees, also known as the supplement angle of 75 degrees, is the angle that when added to 75 results in a sum of 180. Therefore, to calculate the supplement angle of 75 degrees, we subtract 75 from 180. Here is the formula, the math, and the answer:
180 - angle = supplement angle
180 - 75 = 105
105 degrees
75 degrees plus the supplementary angle of 75 degrees equals 180 degrees, which means that together they will make a straight line.
The illustration below shows 75 degrees colored in red and the supplementary angle of 75 degrees, which is 105 degrees, colored in green.
As you can see from the illustration above, 75 degrees and 105 degrees form a straight line together. This proves that the two angles, 75 degrees and 105 degrees, are supplementary angles.
