Brandon buys a sterio for 43.99 in a state we're the sales tax is seven percent how much are the taxes on the sterio and what is the total amount brandon pays for the radio?

< 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

it would open into a square depending on the type of envelope i’m not sure about the second part
