    Answer:

               *Complementary angles add up to 90 degrees,Thus the angle which is equal to its complement is 45 degree.

                *As you know some of the supplementary angles is 180. So lets take the first angle as x. So the value of 1st angle is 36 degree.

                 * In this solution, the one supplement angle is taken by X and twice of supplement angle is 2X. So that it remains two supplement that is measured by angle at 180 degree and then consider it as X x+2x=180°, 3x=180°, x=180÷3=60°, 2×60=120°. Therefore, two supplement angles takes place by 180 degree.

                   *if an angle is twice its complement you can represent the angle as x and other as 2x . since they are complement , there sum is 90 degrees . this means that one angle is 30 deg. the angle that is twice that value is 60 degrees.

                    * Let angle be x. Therefore angle=80 degrees.
