Which ordered pair is the solution to the system of linear equations y = 5x + 8 and y = -4x - 1?
a. (1, -3)
b. (3, -1)
c. (-1, 3)
d. (-3, 1)

< 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
