Lean ground beef costs $7.25 per pound. Which equation best represents y, the total cost of x pounds of lean ground beef? a
x = 7.25 + y
b
y = 7.25 + x
c
x = 7.25y
d
y = 7.25x

< 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
