Sue sees 30 monkeys and 18 baby monkeys at the zoo. What is the ratio of monkeys to baby monkeys?

5:3

Step-by-step explanation:

30:18 = 10:6=5:3

< 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
