Two angles are complementary when they add up to 90 degrees<span>
</span>Two angles are supplementary when they add up to 180 degrees
angle = x
supplementary angle = (180-x)
complementary angle = (90-x)
180 - x - 40 = 2(90-x)
140 - x = 180 - 2x
-x + 2x = 180 - 140
x = 40°

Step-by-step explanation:
(2,2)
x=2 y=2
x+y=4
2+2=4
4=4
5x+5y=20
5(2)+5(2)=20
10+10=20
20=20
