What is the ratio of 132 boys,89 girls, and 14 adults

The required ratio is,

Step-by-step explanation:

We have given,

The number of boys = 132,

The number of girls = 89

And, the number of adults = 14

Therefore, the ratio of boys, girls and adults = the number of boys : the number of girls : the number of adults

=

< 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
