Neda sells televisions. She earns a fixed amount for each television and an additional $ 15 if the buyer gets an extended warranty. If Neda sells 18 televisions with extended warranties, she earns $ 1 comma 170. How much is the fixed amount Neda earns for each television?

$50

Step-by-step explanation:

15x18=270

1170-270=900

900/18=50

< 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
