Julio · Answer 1

40 degrees

x + 140 = 180

x = 40 degrees

Shelby · Answer 2

40 degrees

Step-by-step explanation:

Supplementary angles are angles in which their measures combined add up to 180 degrees. So we can set up an equation:

140+x=180

x=40

So the other supplementary angle is 40 degrees
