What is the angle of C?

∠C = 50°

Step-by-step explanation:

Step 1:

65° + ∠C + 65° = 180°         Supplementary ∠'s

Step 2:

130° + ∠C = 180°          Combine Like Terms

Step 3:

∠C = 180° - 130°         Subtract 130 on both sides

∠C = 50°

step-by-step explanation:

1699/ 8548

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
