Step-by-step explanation:

For (i):

Value of y=80° [opposite angles are EQUAL]

50°+y+x=180°. [SUM of all angles of triangle is

180°]

50°+80°+x=180°

130°+x = 180°

x =180°-130°

x=50°

For (ii):

50°+60°+y=180°. [sum of all angles of triangle

is equal to 180°]

110°+y=180°

y=180°-110°

y=70°

x+y=180°. [LINEAR PAIR]

x+70°=180°

x=180°-70°

x=110°
