Answer 2

Answer:

a=111, b =78

Step-by-step explanation:

triangle ABE is an isosceles triangle with sides AE=BE given

so that means opposite angles to these sides also equal

so angle BAE= angle ABE

so angle ABE= 69

angle ABE and angle EBC are linear pair so they add up-to 180

so

69+a =180

a=180-69

a=111

ED and BC are parallel given

so angle BCD = angle EDF (corresponding angles)

so

b =78
