RE is a line, so angles RPL and EPL form a linear pair and are supplementary.
Supplementary angles are two angles whose measures add up to 180 degrees.
3z + 2z = 180
5z = 180
z = 36
m<RPL = 3z = 3 * 36 = 108
m<EPL = 2z = 2 * 36 = 72
Answer: D. 108 and 72
Answer: The data cannot be modeled by an exponential function because the data is for a linear function (as there is a constant increase in f(x) each time x increases by 1)
Miss girl what is the question?!?! BYE
