Find the sales tax rate.

Write your answer as a percentage.

answer: yes, since the line has a steeper rate of change than the exponential the y-values will be greater and they will only intersect one time.

m∠5 + m∠3 = m∠1   is true.

m∠5 + m∠6 = 180 is true

m∠2 +m∠3 = m∠6   is true

m∠2 +m∠3 +m∠5 = 180   is true
