Answer:
Assumption:-
Let the angles be 5x and 4x
Facts:-
- The sum of angles on a straight line=180°
- Adjacent angles are supplementary i.e there sum is 180°.
Solution:-
According to question:-
5x+4x=180
9x=180
x=20°
If you want to find the angles substitute x
1st angle=5x
=5(20)
=100°
2nd angle=4x
=4(20)
=80°
