Answer 1

Answer:

∠1 = ∠3 ( Opposite angles are equal )

∠3 = 65°

∠1 + ∠2 = 180° ( Linear pair )

65° + ∠2 = 180°

∠2 = 180° - 65°

∠2 = 115°

∠2 = ∠3 ( Opposite angles are equal )

∠3 = 115°

Answer 2

Answer:

Angle 1= 65°

•°• Angle 3= 65°(Vertically Opposite Angles are equal)

•°• Angle 2= (180-65)° (Linear pair)

= 115°

•°• Angle 4= Angle 2= 115° (Vertically Opposite Angles are equal)

Hence, the angles are: 65°, 65°, 115°, 115°.
