Q-2)
1)z = 28 (V.O.a.)
x = 180-28 = 158( linear pair)
y = 158 (V.O.A.)
1)z = 28 (V.O.a.)
x = 180-28 = 158( linear pair)
y = 158 (V.O.A.)

1]given :- z =28' [vertically opposite angles are equal] w.t.k z+x= 180'[linear pair] so,28+x=180 then x=180-28 =152 and x=y=152[vertically opposite angles are equal]
2]given:- 3x and 2x so,3x+2x=180[linear pair are supplementary] 5x=180 thn x=180/5 and x=36
3]given :-3a and 2a and a
so 3a+2a+a=360[complete angle]
6a=360 thn a=60
