If f(x) = 2x²+2x-1, g(x) = x²+5x+2 f(x)=g(x), find the value of x​

just put the values and simpilyfy it untill you get the value of X

hence, the value of X is either 3 or, -1

< 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
