What is the complementary angle of 68.9 degrees? Here we will define the complementary angle of 68.9 degrees, show you how to calculate the complementary angle of 68.9 degrees, and even illustrate the complementary angle of 68.9 degrees (68.9°) so you have a solid understanding of what it means.
The complementary angle of 68.9 degrees, also known as the complement angle of 68.9 degrees, is the angle that when added to 68.9 results in a sum of 90. Therefore, to calculate the complement angle of 68.9 degrees, we subtract 68.9 from 90. Here is the formula, the math, and the answer:
90 - angle = complement angle
90 - 68.9 = 21.1
21.1 degrees
68.9 degrees plus the complementary angle of 21.1 degrees equals 90 degrees, which means that together they will make an L-shaped 90-degree angle.
The illustration below shows 68.9 degrees colored in red and the complementary angle of 68.9 degrees, which is 21.1 degrees, colored in green.
As you can see from the illustration above, 68.9 degrees and 21.1 degrees form an L-shaped angle together. This proves that the two angles, 68.9 degrees and 21.1 degrees, are complementary angles.
