Question

plz give the correct answers wrong answers will be reported. ​

Answer 1

Answer:

1). In given fig. Angle 1 = 120°

• Angle 1 = Angle 3 = 120°(vertically opposite angle)

• Angle 1 + Angle 2 = 180° (linear pair)

120° + Angle 2 = 180°

Angle 2 = 180° - 120°

Angle 2 = 60°

•Angle 2 = Angle 4 = 60° (vertically opposite angle)

• Angle 2 =angle 6 = 60° (corresponding angles )

•Angle 1 = Angle 5 = 120°(corresponding angles )

•Angle 3 = Angle 7 = 120°(corresponding angles)

Angle 4 = Angle 8 = 60°

2). In fig 2

We know that corresponding angles are equal so,

(3x -20)° = (2x + 10)°

3x - 2x = 10 + 20

x = 30°

3). In fig AB || BC and BC || DE

x° + 75° = 180°

x° = 180° - 75°

x° = 105°
