QUESTION :-
Two lines l and m are parallel to each other and t is a transversal. If the ratio of two angles a and b is 2 : 3 . Then find the measure of angles a and b
GIVEN :-
- Ratio of two angles A and B = 2:3
TO FIND :-
- Measures of angles A and B
SOLUTION :-
Let ,
- a = 2x
- b = 3x
From the given digure , a and b are co-interior angles. Their sum is 180°
Then ,
∴ The measures of ∠a and ∠b is 72° and 108°
ADDITIONAL INFO :-
★ Corresponding angles are equal
★ Alternate interior and Alternate exterior angles are equal
★ Vertically opposite angles are equal
★ Two angles are said to be supplementary only when their sum is 180°
