I need help, what is 1/3 ÷ 3 =?​

1/9

Step-by-step explanation:

so you do 1/3 x 1/3 because you need to flip the 2nd number, then you multiply and you get 1/9! 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
