ini jawabannya yg c, d, e jawabannya apa tolong ya pake cara.

sudut satu putaran = 360°
<BOC = < AOD = 108° = < Bertolak belakang
< DOF = < COE = 17° = < Bertolak belakang
< AOE = < BOF = y ( bertolak belakang )
= 360° - [ ( 108° × 2 ) + ( 17° × 2)]
= 360° - ( 216 + 34 )
= 360° - 250°
= 110°/2 =55° ( y )
< AOC = AOE+ <COE
= 55° + 17°
= 72°
