What is the complementary angle of 89 degrees? Here we will define the complementary angle of 89 degrees, show you how to calculate the complementary angle of 89 degrees, and even illustrate the complementary angle of 89 degrees (89°) so you have a solid understanding of what it means.
The complementary angle of 89 degrees, also known as the complement angle of 89 degrees, is the angle that when added to 89 results in a sum of 90. Therefore, to calculate the complement angle of 89 degrees, we subtract 89 from 90. Here is the formula, the math, and the answer:
90 - angle = complement angle
90 - 89 = 1
1 degree
89 degrees plus the complementary angle of 1 degree equals 90 degrees, which means that together they will make an L-shaped 90-degree angle.
The illustration below shows 89 degrees colored in red and the complementary angle of 89 degrees, which is 1 degree, colored in green.
As you can see from the illustration above, 89 degrees and 1 degree form an L-shaped angle together. This proves that the two angles, 89 degrees and 1 degree, are complementary angles.
