Answer:

y = 100 , ∠ AED = 130°

Explanation:

∠ BEC and ∠ BEA are a linear pair and sum to 180° , that is

∠ BEC + 50° = 180° ( subtract 50° from both sides )

∠ BEC = 130°

∠ AED and ∠ BECare vertically opposite angles and are congruent , that is

y + 30 = 130 ( subtract 30 from both sides )

y = 100

Then

∠ AED = y + 30 = 100 + 30 = 130°
