Answer:
given the ratio of two adjacent angles on a straight =5:4
so one angle is =5x and the other angle=4x
we know that two adjacent angles on a straight line always forms a linear pair:
=5x+4x=180degree
=9x=180degree
x=20 degree
therefor one angle =5x=5*20=100
and other angle =4x=4*20=80.
5x=100 degree
4x=80 degree
