PLEASE NO TROLLS I REALLY NEED HELP Use this diagram to answer questions 8 - 10. (Note: Line AB is parallel to line EC)
8. What is the value of x? *
9. What is the measure of ∠A? *
10. What is the measure of ∠D?

yeah guys no trolls

Step-by-step explanation:

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
