Option(4) is the answer because
In triangle ABC and triangle EDC
Angle ABC=angle CDE=70
And,
Angle BCA= angle DCE. ( vertically opposite angles)
=> triangle ABC is similar to triangle EDC. ( A.A congruence rule)
=> angle A= angle E. (Corresponding parts of similar triangles) or (CPST)
Hope this helps ..!!!
