What is the supplementary angle of 149.2 degrees? Here we will define the supplementary angle of 149.2 degrees, show you how to calculate the supplementary angle of 149.2 degrees, and even illustrate the supplementary angle of 149.2 degrees (149.2°) so you have a solid understanding of what it means.
The supplementary angle of 149.2 degrees, also known as the supplement angle of 149.2 degrees, is the angle that when added to 149.2 results in a sum of 180. Therefore, to calculate the supplement angle of 149.2 degrees, we subtract 149.2 from 180. Here is the formula, the math, and the answer:
180 - angle = supplement angle
180 - 149.2 = 30.8
30.8 degrees
149.2 degrees plus the supplementary angle of 149.2 degrees equals 180 degrees, which means that together they will make a straight line.
The illustration below shows 149.2 degrees colored in red and the supplementary angle of 149.2 degrees, which is 30.8 degrees, colored in green.
As you can see from the illustration above, 149.2 degrees and 30.8 degrees form a straight line together. This proves that the two angles, 149.2 degrees and 30.8 degrees, are supplementary angles.
