Which of these strategies would eliminate a variable in the system of equations? 10x + 4y = -2
5x – 2y = 2
Choose all answers that apply:
(A Multiply the top equation by
1/2 then add the equations.
B Add the equations.
C Multiply the bottom equation by 2, then subtract the bottom equation from the top equation.

< 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
