Answer with Step-by-step explanation:
Assuming the two lines are parallel
Angle ABC= Angle BCD [Being alternate interior angles]
Angle BCD=22
Angle BCD+Angle DCE=180 [Angles in a straight line]
22+ Angle DCE=180
Angle DCE=180-22
Angle DCE= 158
Angle DCE= Angle BCF [ Vertically opposite angles]
Angle DCE=158
Angle ECF= Angle BCD [ Vertically opposite angles]
Angle ECF=22
