```							Then angle between vector OB and OA will be 90° now break vector OC into its rectangular components..Like vector OCcos45° along vector OA and OAsin45° along vector OB then add them simple algebraically where |OA|=|OB|=|OC|=R such asR+Rcos45° along vector OA(1+1/√2)RAndR +Rsin45° along vector OB(1+1/√2)RNow apply formula resultant =(A^2 + B^2 + 2ABcos\$)^(1/2) where \$ is angle between themHere \$ = 90°So we have sum =(√2 +1)R
