What is the complementary angle of 20.2 degrees? Here we will define the complementary angle of 20.2 degrees, show you how to calculate the complementary angle of 20.2 degrees, and even illustrate the complementary angle of 20.2 degrees (20.2°) so you have a solid understanding of what it means.
The complementary angle of 20.2 degrees, also known as the complement angle of 20.2 degrees, is the angle that when added to 20.2 results in a sum of 90. Therefore, to calculate the complement angle of 20.2 degrees, we subtract 20.2 from 90. Here is the formula, the math, and the answer:
90 - angle = complement angle
90 - 20.2 = 69.8
69.8 degrees
20.2 degrees plus the complementary angle of 69.8 degrees equals 90 degrees, which means that together they will make an L-shaped 90-degree angle.
The illustration below shows 20.2 degrees colored in red and the complementary angle of 20.2 degrees, which is 69.8 degrees, colored in green.
As you can see from the illustration above, 20.2 degrees and 69.8 degrees form an L-shaped angle together. This proves that the two angles, 20.2 degrees and 69.8 degrees, are complementary angles.
