We hope this detailed article on Complementary and Supplementary Angles has helped you in your studies. The measure of an angle is twenty-nine times the measure of a supplementary angle. Call the unknown supplementary angle's measure x. 2 x + ( 2 x 2) 180 4 x 2 180 4 x 182 x 45.5 The previous example could have asked for some different information. Explanation: Supplementary angles' measures have a sum of 180. Solving this equation gives the value of x. Find the missing measurement in the pair of angles. \(x+38180x180-38142\circ\) Exercises for Complementary and supplementary angles Simplifying Fractions Find the missing measurement in the pair of angles. This means that the angles are supplementary and have a sum of \(180\circ\).
