Let the ratio constant be x
4x+5x=180°(Angle on a straight line is 180°)
9x=180°
x=180°/9
x=20°
Angle 1=4*20=80°
Angle 2=5*20=100°
If any doubt plz comment below.

The two angles are in ratio of 4:5
They are forming the linear pair angles
Let x be the common multiple of the angles,
The angles will be 4x and 5x
The sum of angles in linear pair is 180 degree
Hence,
4x+5x=180 degree
9x = 180
x =180÷9
x = 20 degree
Substituting the value of x,
4x=4×20=80 degree
5x=5×20=100 degree
The measure of angles in linear pair are 80 degree and 100 degree.
Hope it helps you!
