put (FC^�^� E)=y=(CE^� F) (FE^� D)=(FD^� E)=(EF^� D)=60 (DE^� B)=(DB^� E)=180−60−y=120−y (BD^� E)=(ED^� C)180−2(120−y)=180−240+2y=2y−60 (AF^� E)=x+60=2y ⇛ x=2y−60 (FC^� D)=(FD^� C)=((180−(180−2y+60))/2)=y−30 (FD^� E)=(FD^� C)+(CD^� E)=60=2y−60+y−30 3y−90=60 ⇛ y=50 x=2y−60=2×50−60 = 40

put(FCE^)=y=(CEF^)(FED^)=(FDE^)=(EFD^)=60(DEB^)=(DBE^)=180−60−y=120−y(BDE^)=(EDC^)180−2(120−y)=180−240+2y=2y−60(AFE^)=x+60=2y⇛x=2y−60(FCD^)=(FDC^)=180−(180−2y+60)2=y−30(FDE^)=(FDC^)+(CDE^)=60=2y−60+y−303y−90=60⇛y=50x=2y−60=2×50−60=40
