Use quadratic regression to find the eguation for the parabola going
through these 3 points,
(-4, 7) (6, -33) (10, -105)
y = [ ? ]x2 +
X +

Urgent

< 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
