Answer:
110° = ∠AED
Step-by-step explanation:
Four sides polygon. The sum of the angles = (n - 2)180; 4 - 2(180) = 360°
∠B + ∠D + ∠BCD + ∠DEB = 360°
92° + 98° + 86° + ∠DEB = 360°
276° + ∠DEB = 360°
∠DEB = 360° - 276°
∠DEB = 84°
Now ∠AEB + ∠BED + ∠AED = 360° All exterior angles of any polygon = 360°
166° + 84° + ∠AED = 360°
250° + ∠AED = 360°
110° = ∠AED
