Р(АВК)=16 , Р(ВКС)= Р(АВК) , так как ΔАВК=ΔВКС по двум сторонам и углу между ними (АВ=ВС , ВК - общая , ∠АВК=∠СВК)
Р(АВС)=Р(АВК)+Р(ВСК)-2*ВК=2*Р(АВК)-2*5=2*16-10=22
2) ΔDEF: ДК - биссектриса ⇒ ∠КDЕ=∠КDF=68°:2=34°
∠F=180°-(∠EDF+∠DEF)=180°-(68°+44°)=68°
ΔDKF: ∠DKF=180°-(∠KDF+∠DFK)=180°-(34°+68°)=78°
3) Точки, лежащие на серединном перпендикуляре к отрезку, равноудалены от концов этого отрезка ⇒ DC=DB=4 см.
АВ=AD+DB=AD+4 ⇒ AD=AB-4=7-4=3 (см) .
