This is the last question I need help on, thanks for helping me on this.

BC= 70

Step-by-step explanation:

If AC is equal to 140 and B is the midpoint of the line, then that would mean the line would be split in half thus having measures BA and BC. Both of the measures would have half of the full length so that would mean that BA and BC equals 70 since 140/2= 70

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

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
