What is the complementary angle of 39 degrees? Here we will define the complementary angle of 39 degrees, show you how to calculate the complementary angle of 39 degrees, and even illustrate the complementary angle of 39 degrees (39°) so you have a solid understanding of what it means.
The complementary angle of 39 degrees, also known as the complement angle of 39 degrees, is the angle that when added to 39 results in a sum of 90. Therefore, to calculate the complement angle of 39 degrees, we subtract 39 from 90. Here is the formula, the math, and the answer:
90 - angle = complement angle
90 - 39 = 51
51 degrees
39 degrees plus the complementary angle of 51 degrees equals 90 degrees, which means that together they will make an L-shaped 90-degree angle.
The illustration below shows 39 degrees colored in red and the complementary angle of 39 degrees, which is 51 degrees, colored in green.
As you can see from the illustration above, 39 degrees and 51 degrees form an L-shaped angle together. This proves that the two angles, 39 degrees and 51 degrees, are complementary angles.
