Find the missing factor.
2n^2(n - 3) - 4(n - 3) = ( ) (n - 3)

Hey

Here's your answer

The missing factor is (2n^2-4)

Hope it helps.

Good luck on your assignment

< 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
