A bike store sells scooters at a 54% markup if the store sells each scooter for $69.30 then what is their non-markup price

$45

Step-by-step explanation:

1.54(x) = 69.3

Divide both sides by 1.54

x = 45

< 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
