In DeltaABC Seg BD bisects /_ABC . If AB=x, BC=x+5, AD=x-2, DC=x+2 , then find the value of x .

In DeltaABC , ray BD bisects /_ABC . A-D-C , side DE|| side BC , A-E-B . Prove that, (AB)/(BC)=(AE)/(EB) . Complete the activity by filling the boxes. In DeltaABC , ray BD is the bisector of /_ABC :.(AB)/(BC)=square ....... (I) (By angle bisector theorem) In DeltaABC , seg DE|| side BC :.(AE)/(EB)=(AD)/(DC) ........ (II) square :.(AB)/(square)=(square)/(EB) .......[From (I) and (II) ]
