Answer quick

the diagram shows a quadrilateral abcd.
ae is parallel to bc.
ef is the angle bisector of angle aed.

y = 25

Step-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°, thus

y = 180 - (55 + 100) = 180 - 155 = 25

d. you cannot tell because there are no values shown.
