Find the Supplement of the angle 1/3 of 210°. So, the measure of the supplementary angle is 72°. But the angles don't have to be together. Make your child a Math Thinker, the Cuemath way. Because x and 108° are supplementary angles. The meaning of the definition is if we take any two angles and if we add them and if the sum is right angle then we can call them as complementary angles. Given x = 72˚, find the value y. Then find the value of another angle. Example 3: Find the value of the following expression: \[E = \tan {1^\circ }\tan {2^\circ }\tan {3^\circ }.......\tan {89^\circ }\].

If the sum of two angles are 180o then the angles are said to be supplementary angles,  .

In this case, the measure of rotation that is the angle formed between the initial side and the terminal side is represented by Ɵ.

Instead, when you add two complementary angles together, they total 90 degrees. The measures of two angles are (x + 25)° and (3x + 15)°. What is the measure of a supplementary angle? When the sum of two angles is 90°, then the angles are known as complementary angles. For the first two terms, we note that, \[\begin{array}{l} \cos {58^\circ } = \sin \left( {{{90}^\circ } - {{58}^\circ }} \right) = \sin {32^\circ }\\ \sin {22^\circ } = \cos \left( {{{90}^\circ } - {{22}^\circ }} \right) = \cos {58^\circ } \end{array}\]. Two Angles are Complementary when they add up to 90 degrees (a Right Angle).
