The cost of a ticket t to a concert with a 3% sales tax can be represented by the expression t+0.03t. simplify the expression. then determine the total cost after sales tax if the original price was $72.

109 is the nearest whole number/final answer! : )

< 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
