Angles B and C are alternate interior angles where transversal BC cuts parallel lines AB and CD. Thus angles B and C are equal. Angle B is 65°.

Angle AEC is the exterior angle opposite interior angles A and B, which means its value is the sum of angles A and B.

∠AEC = ∠A +∠B = 47° +65°

∠AEC = 112°
