If an equation is an identity how many solutions does it have?

infinite solutions

Step-by-step explanation:

If we have and identity such as

3=3

Then we have infinite solutions since the identity is always true

< 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
