AED = EAB + ABE (Exterior angle is equal to sum of interior opposite angles) --> AED - ABE = EAB = 30
Alternatively,
ABE = 150 - AEB
AEB = 180 - AED
ABE = 150 - (180 - AED)
ABE = AED - 30
AED - ABE = 30
Answer: A
Alternatively,
ABE = 150 - AEB
AEB = 180 - AED
ABE = 150 - (180 - AED)
ABE = AED - 30
AED - ABE = 30
Answer: A

Vyshak Please correct the highlighted part...
if one follow figure
angle 3=angle 2+angle 1(ext. angle property)
as angle 1= 30 (given)
angle 3-angle 2=angle 1---->30
or AED-ABE=30
Ans A
