Two angles are supplementary. The first angle measures 40 degrees. What is the measurement of the second angle

Supplementary angles add up to 180º
If one is 40º, then the other is (180º-40º) = 140º

None of those choices describes a plane.
choice C is the only example of a plane.

Two angles are supplementary so this mean adding them measure give 180 degrees
- first angle measure 40 degree so the measure of supplement angle will be
180 -40 = 140 degrees
