Two or more angles are supplementary if their sum is 180. An angle is twice the size of its supplement. Set up and solve an equa
vekshin1

Answer:

  • angle: 120°
  • its supplement: 60°

Step-by-step explanation:

Let "a" represent the measure of the angle. Then 180-a is the measure of its supplement. Your equation can be ...

  a = 2(180-a) . . . an equation

  a = 360 -2a . . . . eliminate parentheses

  3a = 360 . . . . . . add 2a

  a = 120 . . . . . . . . divide by 3 to find "an angle"

  180-a = 60 . . . . . find "its supplement"

The measure of the angle is 120°, of its supplement, 60°.
