Answer:

110° = ∠AED

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
