Question

plz answer this question it's urgent plz!!!​

Answer 1

Step-by-step explanation:

Given:- Angle ADF=130°

Angle C or ECB =50°

I) Angle ADF + Angle ADE = 180° (linear pair)

130° + Angle ADE = 180°

Angle ADE = 180° - 130°

Angle ADE = 50°

ii) Angle ABC = Angle ADE = 50° (corresponding angles)

iii) Angle DEC + Angle ECB = 180° (co-interier angles)

DEC+50°=180°

DEC=130°

hope it helps
