Evelyn has 16 pink beads and 32 purple beads to make identical bracelets. She puts a half as many pink beads as purple beads on each bracelet, and she uses all of the beads.

< 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
