What is the complementary angle of 86.4 degrees? Here we will define the complementary angle of 86.4 degrees, show you how to calculate the complementary angle of 86.4 degrees, and even illustrate the complementary angle of 86.4 degrees (86.4°) so you have a solid understanding of what it means.
The complementary angle of 86.4 degrees, also known as the complement angle of 86.4 degrees, is the angle that when added to 86.4 results in a sum of 90. Therefore, to calculate the complement angle of 86.4 degrees, we subtract 86.4 from 90. Here is the formula, the math, and the answer:
90 - angle = complement angle
90 - 86.4 = 3.6
3.6 degrees
86.4 degrees plus the complementary angle of 3.6 degrees equals 90 degrees, which means that together they will make an L-shaped 90-degree angle.
The illustration below shows 86.4 degrees colored in red and the complementary angle of 86.4 degrees, which is 3.6 degrees, colored in green.
As you can see from the illustration above, 86.4 degrees and 3.6 degrees form an L-shaped angle together. This proves that the two angles, 86.4 degrees and 3.6 degrees, are complementary angles.
