PLEASE HELP ME WITH THIS Dado f(x)
==
4x2 – 3x + 2 y g(x) = 3x + 1
Encuentre lo siguiente:
Parte a:f(x) + g(x)
Parte b: f(x) - g(x)
Parte c: f(x) · g(x)

4/10

Step-by-step explanation:

< 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
