Answer:
The angles are 60° and 120°.
Explanation:
"supplementary" means that the two angles add up to 180°.
One angle can be x.
The other angle can be x+60° bc its 60° more.
Write an equation.
x + x + 60 = 180
combine like terms.
2x + 60 = 180
subtract 60
2x = 120
divide by 2
x = 60.
Since x = 60, one angle is 60° and the other is 120° (that's 60° more) and they are supplementary.
60° + 120° = 180°
The angles are 60° and 120°.
