Answer:
angle F = 120 because FBCD is a parallel rectangle and by rule, the angle C and F will be equal
now calculate
FECB contains that angle and by chance this also a rectangle
we know every rectangle makes 360 degree of angle
see equation
120 + 120 + 100+ x = 360
hence x= 20 degree
and y = 50 degree this is easy
