Answer 1

Answer:

a = 50

b = 130

c=130

Step-by-step explanation:

a = 50 ( vertical opposite angles )

50 + b = 180 ( Linear pair)

b = 130

b=c =130 ( vertical opposite angles )

Answer 2

Answer:

a= 50° (vertically opposite angle)

let b&c be x

50°+50°+x+x =360°

100°+2x =360°

2x = 360° - 100°

2x=260°

x = 260°/2

x = 120°

hence, b & c is 120°
