A city plans to spend $28,415,730 on a bridge construction project. For one thousand dollars more, the city can install a dedication plaque. How much will the bridge cost including the plaque?

< 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
