Answer:
let the ratio be 5x and 4x. 5x+4x=180 because sum of supplementary angles are 180. . 9x=180. ,x=20. 5x=5*20=100 and 4x=4*20=80

Answer:
let the angles be x
As there are in the ratio of 4:5,we can write it as 4x and 5x
according to the question
4x+5x=180
9x=180
x=180/9
x=20
therefore, 1st angle =4x
=4×20
=80°.............(i)
and 2nd angle =5x
=5×20
=100°.............(ii)
