Answer quick The diagram shows a quadrilateral ABCD.AE is parallel to BC.EF is the angle bisector of angle AED.
Accepted Solution
A:
Answer:y = 25Step-by-step explanation:Since AE and BC are parallel, then∠AED = ∠BCE = 110° ( corresponding angles )Since EF is the angle bisector of ∠AED, then∠AEF = ∠FED = 55°∠AFE and ∠DFE form a straight angle, thus∠AFE = 180° - 80° = 100°The sum of the angles in ΔAEF = 180°, thusy = 180 - (55 + 100) = 180 - 155 = 25
