`A B ,\ C D ,\ a n d\ E F` are three concurrent lines passing through the point `O` such that `O F` bisects `/_B O Ddot` If `/_B O F=35^0,` find `/_B O C` and `/_A O Ddot`
<`A B ,\ C D ,\ a n d\ E F`are three concurrent lines= passing through the point `O`.
`/_dof=/_bof=35^0`
Also AB is straight line `,/_AOD+/_DOF+/_BOF=180`
`/_AOD+35+35=180`
`/_AOD=180-70=110`
`/_AOD=/_BOC`
/_BOC=110`
