Find the ratio in simplest form.

4/9 or 4:9 or 4 to 9.

Step-by-step explanation:

We need to find the ratio 2/3 to 3/2 in simplest form.

The given ratio can be written in the fraction form as

On simplification, we get

Therefore, the required ratio is 4/9 or 4:9 or 4 to 9.

< 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
