There are three times as many cats in the animal shelter as puppies. There are twelve times as many fish as there are puppies. If there are 12 cats, how many fish and puppies are at the shelter?

12 fish and puppies

Step-by-step explanation:

There is  1  fish for every  3 puppies. So that is  4  animals in  1  "set".

We have   "sets", which means  4  sets.

4 fish per "set" and  3 "sets" means there are  

4 × 3  or  12 fish and puppies.

< 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
