Well if it is a supplement then that means that is has to equal 180 degrees. If one angle is two times the other and it equals to 180 you can make an equation out of this.
First you would do:
x+2x=180
Then
3x=180
Last
x=60
Therefore x will equal 60 degrees which means that angle 1 is 60 and angle 2 is 120

-2 is an integer...and it is rational because it can be made into a fraction..-2/1
