Answer:
(a) 110° = y -------- opposite angle
y + x = 180°------ interior angle are supplementary
110 +x = 180°
x = 180 - 110
x = 70°
(b) x + 2x = 180° ------- interior angle
3x =180°
x = 180 ÷ 3
x = 60
and also 2x = 2 × 60 = 120°
(c)x = 120° ------- corresponding angle of 120°.
y =70° ----------- interior alternate angle of 70°
plzz.... follow if it helped...

(α) 110° = opposite angle.
=> y + x = 180°---------- interior angles are supplementary.
=> 180° - 110°
=> 70° ANS.
________________________________
(b) x + 2 = 180° = interior angle.
=> 3x = 180°
=> x = 180/3
=> x = 60° ANS.
_____________________
(c) x = 120° corresponding angle 120°
=> y = 70° interior angle 70°
