10

Step-by-step explanation:

So there are 5 pieces of rope, if you cut them all in half then that would double the number.

10

Step-by-step explanation:

5 divided by 1/2 is 10

< 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
