what are the factors of 5x2 + 39x − 8? (5 points)

(5x − 4)(x + 2)
(5x − 2)(x + 4)
(5x − 1)(x + 8)
(5x − 8)(x + 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
