7.5g of sugar is needed for every cake made. How much sugar is needed for 7 cakes?

52.5g

Step-by-step explanation:

You do 7.5 × 7 which equals 52.5g

< 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
