90 degreesTwo angles are complementary if their sum is equal to 90 degrees12345. In a right triangle, the sum of the other two angles except the right angle is equal to 90 degrees2. The complement of any angle is the value obtained by subtracting it from 90 degrees24. For complementary angles, the sine of one angle is equal to the cosine of the other angle, and vice versa. The tangent of one angle is equal to the cotangent of the other angle, and vice versa. Finally, the secant of one angle is equal to the cosecant of the other angle, and vice versa5.Learn more:✕This summary was generated using AI based on multiple online sources.

Similarly, when we can learn here the trigonometric identities for complementary angles. Sin (90 – θ) = Cos θ Cos (90 – θ) = Sin θ Tan (90 – θ) = Cot θ Cot (90 – θ) = Tan θ Sec (90 – θ) = Csc θ Csc (90 – θ) = Sec θbyjus.com/maths/trigonometric-identities/Any two angles are said to be complementary if their sum is equal to 900. So, complement of any angle is the value obtained by subtracting it from 900. In a right triangle, the sum of the other two angles except the right angle is equal to 900. Therefore, these two angles are considered to be the complementary angles.
www.vedantu.com/maths/trigonometric-ratios-of-co…The two angles, say ∠X and ∠Y are complementary if, ∠X + ∠Y = 90° In such a condition ∠X is known as the complement of ∠Y and vice-versa. In a right angle triangle, as the measure of the right angle is fixed, the remaining two angles always form the complementary as the sum of angles in a triangle is equal to 180°.byjus.com/maths/trigonometric-ratios-of-compleme…The angles of a right triangle in terms of its sides are denoted by six trigonometric ratios. If the sum of any two angles equals 90 degrees, they are said to be complementary. Therefore, the value obtained by deducting it from 90 degrees is the complement of any angle.
