Supplementary angles are two angles that add to 180 degrees.

The equation is 4x + 5x = 180.

(combine like terms and simplify) 9x=180

180/9=20

so x = 20

So that would mean 4x= 80.

The smaller angle is equal to 80. Since supplementary angles add up to 180, you have a clue as to what the larger angle measures to.
