Two hamburgers and a coke cost $2.35. three hamburgers and two cokes cost $3.85. how much does a hamburger cost as well as a coke?

< 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

i belive those are the ones that are under 90 degreese.
