Step-by-step explanation:

The angle marked x is an exterior angle of the polygon.

The sum of the measures of the exterior angles of a polygon, one exterior angle per vertex, is 360 deg.

In a regular polygon, all exterior angles are congruent. The number of exterior angles, one per vertex, is the same as the number of sides.

We count the number of sides of this polygon and see it has 9 sides.

Since it is a regular polygon, he measure of each exterior angle is 360 divided by the number of sides.

x = 360 deg/9 = 40 deg

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
