Aweek before election 1,500 people were asked who they planed to vote for, 45% said they planned to vote for candidate x. 38% said they planned to vote for candidate y. the rest said they weren't sure .how many of the people who were asked have not yet decided for whom they plan to vote?

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30
