If the two angles are in ratio 2:3, then :-
Let the angles be 2x° and 3x°.
Supplementary angle = 180°
2x °+ 3x° = 180°
5x° = 180°
x = 180°/5°
x = 36°
Therefore, 2x° = (2*36)° =72°
& 3x° = (3*36)° = 108° Ans.
Ans.) If one angle is 108° then the other angle is 72°.
Checking:-
Two angles = 72°/108° = 2/3 =2:3
Let the angles be 2x° and 3x°.

Ans.) If one angle is 108° then the other angle is 72°.
Checking:-
Two angles = 72°/108° = 2/3 =2:3
