CONSTRUCTION are givine in attachments :-
DIAGRAM A) :-
GIVEN :-
Y = ?
X = ?
SOLUTION :-
105 + Y = 180° .......linear pair
Y =180 - 105
Y = 75°
therefore,
Y = X .......... alternate angle
Y = X = 75°
X = 75°
DIAGRAM B) :-
GIVEN :-
Z = ?
Y = ?
X = ?
SOLUTION :-
Z = 70° ........ alternate angle
hence,
Z + Y = 180° ..... linear pair
70 + Y = 180°
Y = 180 - 70
Y = 110°
therefore,
X = Y ...... corresponding angle
X = Y = 110°
X = 110°
