Elizabeth has a piece of ribbon that is 4.5 m long she wants to cut into pieces that are 0.25 m long how many pieces of ribbon

4.5 / 0.25 = 18

18 pieces of ribbon

< 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
