Please solve it

Dear student
Lines AB || PC ,SO angle BCF=angle NBA=35 Degree( Corresponding angles) .
Now Angle NBA= Angle NBK ( angle of incidence = angle of reflection )
Now angle NBK= angle CBF ( Vertically opposite)
Now angle BFP= Angle(CBF+BCF)( Exterior angle property) angke BFP = 35+35=70 Degree.
regards.
