Find the supplement of the angle 2/3 of 90°. Therefore, a complement of the angle 4/5 of 90° = 18°Ħ. Find the complement of the angle 4/5 of 90°. Therefore, the required angles are 18°, 72°.ĥ. Let, the first angle = x degrees, then, Second angle = (90 – x)degrees Given that the difference between two complementary angles is 54°. The difference between two complementary angles is 54°. Move 4 to the right side and divide it from 140°.Ĥ. Move 40° to the right side and subtract it from 180°. We know that, Sum of Supplementary angles = 180 degrees. Find the value of x if angles are supplementary angles. The measures of two angles are (x + 15)° and (3x + 25)°. Therefore, Supplement of the angle 1/4 of 200° is 130°ģ. Find the Supplement of the angle 1/4 of 200°.īy adding 130 degrees to 50 degrees, the total angle becomes 180 degrees. We know that Sum of Complementary angles = 90 degrees.īy adding 40 degrees to 50 degrees, the total angle becomes 90 degrees.Ģ. The given angle is 50 degrees, then, the Complement is 40 degrees. Solved Examples on Supplementary and Complementary Angles In Supplementary Angles, both angles are said to be a supplement to each other. By adding 130 and 50 degrees, it forms a straight line. If x is one angle then (180 – x)° is the other angle in Supplementary Angles.įor example, if 130° is one angle in Supplementary Angles, then the other angle will be 50°. Two angles are added and formed a straight line in Supplementary Angles. The two angles are said to be Supplementary angles if their sum is 180°. Also, two obtuse angles cannot complement each other.Two right angles cannot complement each other.Two complementary angles are acute but vice versa is not possible.70° and 20° complement each other.Įxample 1: To find the complement of 3y + 52°, subtract the given angle from 90 degrees.ĩ0º – (3y + 52º) = 90º – 3y – 52º = -3y + 38º If x° is one angle then (90 – x)° is the other angle in Complementary Angles.įor example, if 70° is one angle in Complementary Angles, then the other angle will be 20°. Each angle is called the complement of the other. The two angles are said to be complementary angles if their sum is one right angle i.e. Also, we have given all the concepts available in Lines and Angles on our website. Find different problems on Supplementary and Complementary Angles in this article. Or else, if the sum of the two angles is 180º, they are called Supplementary angles. If the sum of the two angles is 90º, they are called Complementary angles. Complementary and Supplementary Angles are the angles formed by adding two angles.
