Answer:
Complementary Angles
When the sum of two angles is 90°, then the angles are known as complementary angles. In other words, if two angles add up to form a right angle, then these angles are referred to as complementary angles. Here we say that the two angles complement each other.
Suppose if one angle is x then the other angle will be 90o – x. Hence, we use these complementary angles for trigonometry ratios, where on ratio complement another ratio by 90 degrees such as;
sin (90°- A) = cos A and cos (90°- A) = sin A
tan (90°- A) = cot A and cot (90°- A) = tan A
sec (90°- A) = cosec A and cosec (90°- A) = sec A

Answer:
Explain complementary angles
Step-by-step explanation:
Two angles are called complementary if their measures add to 90 degrees, and called supplementary if their measures add to 180 degrees. ... For example, a 50-degree angle and a 40-degree angle are complementary; a 60-degree angle and a 120-degree angle are supplementary.
