Trinity took some photos. the number of photos she took is a two digit number. the sum of the digits is 11. the tens digit is 3 more than the ones digit. how many photos did trinity take?

< 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
