Question

in the figure ab=bc=cd=de=ef and af=ae.then angle a is​

Answer 1

Step-by-step explanation:

since cd=DE=EF=FG

thus angle COD=DOE=EOF=FOG=40°-----{equal chords subtend equal angles at centre}

angle COG=angle COD + DOE + EOF+FOG

=40+40+40+40

=160°

reflex angle COG=360-angle COG

reflex angle COG=360-160

=200°
