Write a function rule to describe the the amount of change c(x) you get from a $20.00 bill if you buy x pounds of candy at $2.25 a pound. c(x) = 20x + 2.25 c(x) = 20x - 2.25 c(x) = 20 - 2.25x c(x) = 20 + 2.25x w

< 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
