If we travel 400 miles and used 11 gallons of gas, how much would our trip cost us if gas was priced at $2.03 a gallon?

$22.33

Step-by-step explanation:

2.03 x 11 = 22.33

< 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
