Sarah is buying flour for her bake shop. The prices of four types of flour are listed. wheat flour- 5lb for $12.50
Rice flour- 8lb for $24.00
Corn flour- 15lb for $33.75
soy flour- 24lb or $55.20

which type of flour costs the least per pound?

step-by-step explanation:

< 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
