Which system of equations does not have the same solution?
a) 3x+6y = 15
c) x+2y = 5
2x+y=4
6x + 3y = 12
b) 4x + 8y = 20
d) x+2y = 5
2x + y = 4
4x + 2y = 12
Show your work:
b) Explain: How did you get your answer?

< 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
