Question

Find
the
values
of

x
and
y.


i
ii​

Answer 1

Step-by-step explanation:

I) y=80°(V.O.A.)

BY angle sum property

80+50+x=180

x=180-80-50

x=50°

ii) by angle sum property

60+50+y=180

y=70°

x=180-70

x=110°

Answer 2

Answer:

(i) y = 80° & x = 50°

(ii) x = 110° & y = 70°

Step-by-step explanation:

(i) y = 80° [ vertically Opposite angles]

x + 80° + 50° = 180° [ Angle sum property]

x = 180° - 130° = 50°

(ii) x = 60° + 50° [external angle = opposite interior

angle]

x = 110°

y + 110° = 180°

y = 180° - 110° = 70° [sum of external angle and internal angle is 180°]
