2y- x = 8
2y-X = 8
2y-X = 8
-2y+4x = 10
3x = 18
y-2x = -5
3x = 18
Which solution can be used to fill in both blanks in the table?
O (1,6)
(6, 1)
0 (7,6)
(6,7)

< 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
