If m || n, m angle 1 = 4x - 6, and m angle 7 = 2x + 40, then what is m angle 1?

∠1 = 86 degrees

Step-by-step explanation:

alternate exterior angles are equal

4x - 6 = 2x + 40

-2x         -2x

2x - 6 = 40

     +6     +6

2x = 46

2      2

x = 23

∠1 = 4x - 6

∠1 = 4(23) - 6

∠1 = 92 - 6

∠1 = 86

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
