The polygons in each pair are similiar help find the missibg length???

x = 40.

Step-by-step explanation:

The corresponding sides are in the same proportion so:

45/ 27 = 30/18 = x/24

Consider the last 2 fractions:

30/18 = x/24

5/3 = x/24           Cross multiply:

3x = 5 * 24

x =  120 / 3

x  = 40.

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
