Answer 1

Answer:

2=50° (Vertically opposite angles are equal)

5=60° (" " ")

8=70° (" " ")

Now,

1=130°(because both 1 and 3 are V.O.A)

3=130°(" " " ")

4=120°(because both 4 and 6 are V.O.A)

6=120°(" " ")

7=110°(as both 7 and 9 are V.O.A)

9=110°(" " ")

VERTICALLY OPPOSITE ANGLES ARE EQUAL.

Answer 2

Step-by-step explanation:

Angle 2 = 50. [ vertically opposite angles]

Angle 1 + 50. = 180 [ linear pair angles]

Angle 1 = 130

Angle 3 = Angle 1 [ Vertically opposite angles]

Angle 3 = 130

Angle 5 = 60. [ vertically opposite angles]

Angle 5 + Angle 4 = 180. [Linear pair angles]

Angle 4 = 120

Angle 6 = Angle 4

Angle 6 = 120

Angle 8 = 70. [vertically opposite angles]

Angle 8 + Angle 9 = 180 [linear pair angles]

Angle 9 = 110

Angle 7 = Angle 9. [vertically opposite angles]

Angle 7 = 110
