ABCDEF is regular hexagon with point O as centre. The value of `overset(rarr)AB+overset(rarr)AC+overset(rarr)AD+overset(rarr)AE+overset(rarrAF) n xx overset(rarr)AO` is . Find n.

Text Solution

Verified by Experts

The correct Answer is:
6
`bar(AB)+barAF=barAO rarr barAB=barAO-barAF`
`barAC=barAB+barAO,barAD=bar2AO,barAE=barAO+barAF`
`-5barAO+barAB+barAF=bar5AO+barAO=6barAO`
