I hope it is helpful to you and others. Please mark me as brainliast.

Step-by-step explanation:

(i) = y = 80° ( Vertically Opposite Angle )

= 50° + 80° + x = 180° (Angle Sum Prop. )

= 130 + x = 180

= x = 180 - 130

= x = 50°

(ii) = y + 50° + 60° = 180° ( Angle Sum Property )

= y + 110 = 180

= y = 180 - 110

= y = 70°

= 70° + x = 180° ( Linear Pair )

= x = 180 - 70

= x = 110°
