Plz hurry it's !
which pair of numbers is relatively prime?
a. 24 and 45 b. 12 and 25 c. 9 and 24 d. 18 and 39

B. 12 and 25 is the answer

Hope this helps!

< 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
