Question

Answer correct wanna reported​

Answer 1

angle "a" is 130°

as vertically opposite angles are equal

angle b is 130°

as pair of corresponding angles are equal

angle b + angle c = 180°

since interior angles on the same side of transversal are supplementary

so , angle c = 180°-130°=50°

now , angle c= angle d

since vertically opposite angles are equal

so , angle d = 50°

hope its helpful

Answer 2

Answer:

130 = Angle b = 130°

Angle d +Angle b = 180°

Angle d + 130 = 180

Angle d = 180-130

Angle d = 50°

Angle d = Angle c = 50°

Angle c + Angle a = 180

50° + Angle a = 180

Angle a = 180-50 = 130°
