Hello ! Guys here's Ur ans...
Given :
< 110°.
70°. and AB || CD.
To Find : Value of X and Y .
Solution : Y = 110 ( vertically opposite angles).
X = 110 ( corosponding angles ).
Hope ! it's helpful...thnx.. follow..if wanna support me...
ANSWER :-
TO FIND :-
SOLUTION :-
▪︎x + 70° = 180° [ Linear pair ]
▪︎x = 180° - 70°
▪︎x = 110°
Here, 1 + 110° [ Linear pair ]
=> 1 = 180° - 110°
=> 1 = 70°
Again by linear pair,
=> 1 + y = 180°
=> y = 180° - 70°
=> y = 110°
Here we found,
=> x = y = 110°
Therefore, by alternate interior angle property,
AB || CD
