if AB||CD then AF is a transversal and if is a transversal , then angle BAF = angle AFC = 80° ( alternative interior angles )
angle AFD + angle AFC = 180° ( linear pair )
angle AFD = 100°
and angle CFE = 100° as they are vertically opposite angles
and then we would apply ASP ( angle sum property)
C+F+D= 180°
C=35°
hope it helps
