Three pounds of lawn seed covers 1800 square feet. How many bags are needed
to cover 8400
square
feet?

< 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

the answer is d

for problems like this theres an app, its photomath that explains the problem and gives the answer hope i
