Define these sets by listing their elements:

The set of all odd 2-digit numbers that have the digit 3 in them

PLS HELP!!!

{13,23,33,43,53,63,73,83,93}

Step-by-step explanation:

These are the conditions given for the set.

So our goal is to get the set of all odd numbers between 10 and 99 that have 3 in them.

The elements of the set are:

{13,23,33,43,53,63,73,83,93}

< 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
