A light tower is going to be installed on the left edge of the Skywalk as
indicated in the diagram above. The light will shine down to the
opposite edge of the Skywalk indicated with the star in the diagram
above. How tall does the light tower need to be if the angle of
depression is 51?

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
