Please double check if the following interpretation corresponds to the original question.

When Arjun makes hot cocoa, he adds 20 mL of chocolate syrup for every 3 ounces of hot water.

Arjun's brother, Eli, adds 45 mL of chocolate syrup for every 6 ounces of hot water.

Which hot cocoa is more chocolatey?

1 oz. fl = 28.35 mL.

Arjun:

Total liquid = 20 + 3*28.35 mL = 105.05 mL

percentage of chocolate = 20/105.05 = 19.0%

Brother:

Total liquid = 45 + 6*28.35 mL = 215.1 mL

percentage of chocolate = 45/215.1 = 20.9%

Conclusion: Cocoa of Arjun's brother is more chocolatey

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
