x = 35

y = 100

Step-by-step explanation:

∠AEB and ∠DEC are vertical angles because they are opposite each other; they are also equal because of this. We can write an equation to model the situation:

∠AEB = ∠DEC

50° = x° + 15°

x = 35

∠AEB and ∠AED are supplementary because the form a line; this means they add up to 180°

∠AEB + ∠AED = 180°

50° + y + 30° = 180°

y + 80°  = 180°

y = 100
