What is the supplementary angle of 143.4 degrees? Here we will define the supplementary angle of 143.4 degrees, show you how to calculate the supplementary angle of 143.4 degrees, and even illustrate the supplementary angle of 143.4 degrees (143.4°) so you have a solid understanding of what it means.
The supplementary angle of 143.4 degrees, also known as the supplement angle of 143.4 degrees, is the angle that when added to 143.4 results in a sum of 180. Therefore, to calculate the supplement angle of 143.4 degrees, we subtract 143.4 from 180. Here is the formula, the math, and the answer:
180 - angle = supplement angle
180 - 143.4 = 36.6
36.6 degrees
143.4 degrees plus the supplementary angle of 143.4 degrees equals 180 degrees, which means that together they will make a straight line.
The illustration below shows 143.4 degrees colored in red and the supplementary angle of 143.4 degrees, which is 36.6 degrees, colored in green.
As you can see from the illustration above, 143.4 degrees and 36.6 degrees form a straight line together. This proves that the two angles, 143.4 degrees and 36.6 degrees, are supplementary angles.
