Answer:
Associative Property
Step-by-step explanation:
To associate means to connect or join with something. According to the associative property of addition, the sum of three or more numbers remains the same regardless of how the numbers are put together.
Let the "other" angle be x. Then we can set up the equation: 2x + 60 + x = 180, because supplementary means that the angles add up to 180 degrees.
We get:
3x + 60 = 180
3x = 120
x = 40.
2(40) + 60 = 80 + 60 = 140.
So one angle is 140 degrees and the other angle is 40 degrees.
