What is the supplementary angle of 105.1 degrees? Here we will define the supplementary angle of 105.1 degrees, show you how to calculate the supplementary angle of 105.1 degrees, and even illustrate the supplementary angle of 105.1 degrees (105.1°) so you have a solid understanding of what it means.
The supplementary angle of 105.1 degrees, also known as the supplement angle of 105.1 degrees, is the angle that when added to 105.1 results in a sum of 180. Therefore, to calculate the supplement angle of 105.1 degrees, we subtract 105.1 from 180. Here is the formula, the math, and the answer:
180 - angle = supplement angle
180 - 105.1 = 74.9
74.9 degrees
105.1 degrees plus the supplementary angle of 105.1 degrees equals 180 degrees, which means that together they will make a straight line.
The illustration below shows 105.1 degrees colored in red and the supplementary angle of 105.1 degrees, which is 74.9 degrees, colored in green.
As you can see from the illustration above, 105.1 degrees and 74.9 degrees form a straight line together. This proves that the two angles, 105.1 degrees and 74.9 degrees, are supplementary angles.
