Aline has a slope of -1/2 and a y-intercept of 3.
which equations represent the line?
choose all answers that are correct.
a. 2y = 6 + x
b. x + 2y = 6
c. y = -1/2x + 3
d. (y - 2) = -1/2( x - 2 )

< 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
