What is the complementary angle of 85.9 degrees? Here we will define the complementary angle of 85.9 degrees, show you how to calculate the complementary angle of 85.9 degrees, and even illustrate the complementary angle of 85.9 degrees (85.9°) so you have a solid understanding of what it means.
The complementary angle of 85.9 degrees, also known as the complement angle of 85.9 degrees, is the angle that when added to 85.9 results in a sum of 90. Therefore, to calculate the complement angle of 85.9 degrees, we subtract 85.9 from 90. Here is the formula, the math, and the answer:
90 - angle = complement angle
90 - 85.9 = 4.1
4.1 degrees
85.9 degrees plus the complementary angle of 4.1 degrees equals 90 degrees, which means that together they will make an L-shaped 90-degree angle.
The illustration below shows 85.9 degrees colored in red and the complementary angle of 85.9 degrees, which is 4.1 degrees, colored in green.
As you can see from the illustration above, 85.9 degrees and 4.1 degrees form an L-shaped angle together. This proves that the two angles, 85.9 degrees and 4.1 degrees, are complementary angles.
