Which value, when placed in the box, would result in a system of equations with infinitely many solutions? y = -2x + 4
6x + 3y = |_|
-12
-4
4
12

< 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
