The Bank of France sells U. S. dollars ($) at a rate of ($1.40)/(€1) and buys U. S. dollars at a rate of ($1.80)/(€1). At the beginning of a trip, Sandra exchanged $420 to get €200. At the end of the trip, she is left with €36, so she exchanges the €36 back to U. S. dollars. How many U. S. dollars will Sandra receive in exchange?

< 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
