kilograms per dollar?

9.534 kg per dollar is the better deal

Step-by-step explanation:

when you covert 9.534 kg to lb you'll get 21.019 pounds which is a much better deal than 4, and because 21>4

< 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
