let the angles be 4x and 5x.
4x+5x=180°
9x=180°
x=180°÷9
x=20°
So 4x=4×20°=80°
5x=5×20°=100°
SO..the angles are 80° and 100°..

since we know sum of supplementary angles =180
therefore...
4x+5x=180
9x=180
x=180÷9
x=20......
therefore putting value of x in angles.we get
4x=4×20=80..and
5x=5×20=100.....ans.....
