40 degrees

Step-by-step explanation:

180-140=40

y = 40

Step-by-step explanation:

To find a missing measure in an angle proven to be suppplementary, subtract the existing measurement from 180.

in this equation, the existing measure is 140 degrees, and the measure in question is y.

subtract 140 from 180 to get 40

180 - 140 = 40

therefore, y = 40
