Which system of equations does not have a real solution? O y=x2 + 3 x- 5 and 4 x + 5y = 20
Oy= x2 + 3x - 5 and x + y = -10
O y=x2+3 x-5 and x + y = -9

< 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
