What is the complementary angle of 15 degrees? Here we will define the complementary angle of 15 degrees, show you how to calculate the complementary angle of 15 degrees, and even illustrate the complementary angle of 15 degrees (15°) so you have a solid understanding of what it means.
The complementary angle of 15 degrees, also known as the complement angle of 15 degrees, is the angle that when added to 15 results in a sum of 90. Therefore, to calculate the complement angle of 15 degrees, we subtract 15 from 90. Here is the formula, the math, and the answer:
90 - angle = complement angle
90 - 15 = 75
75 degrees
15 degrees plus the complementary angle of 75 degrees equals 90 degrees, which means that together they will make an L-shaped 90-degree angle.
The illustration below shows 15 degrees colored in red and the complementary angle of 15 degrees, which is 75 degrees, colored in green.
As you can see from the illustration above, 15 degrees and 75 degrees form an L-shaped angle together. This proves that the two angles, 15 degrees and 75 degrees, are complementary angles.
