70 degrees

Explanation:

Supplementary angles sum to 180 degrees. Let our angle be A. Then A=40+(180-A)=220-ArArr2A=220rArrA=110.

So our angle is 110 degrees, and its supplement is 70 degrees.

70^@

Explanation:

Let the supplement angle be x. Therefore the measure of the bigger angle is x+40. Since the sum of supplementary angles add up to 180^@, we get:

x+x+40=180

2x+40=180

2x=140

x=70
