Remark
<u>Two facts.</u>
1) Tan(x) = Sin(x) / Cos(x)
2) Csc(x) and Sin(x) are reciprocal relationships. When multiplied together, they equal 1.
Solution
So Csc(x) * tan(x) = csc(x) * sin(x) / cos(x) = 1/cos(x) = sec(x)
So far what we have is tan^2(x) + sec(x). We have to get rid of tan^2(x)
Use the identity of 1 + tan^2(x) = sec^2(x)
tan^2(x) = sec^2(x) - 1
sec^2(x) - 1 + sec(x)
a^2 + a - 1 <<<<<< Answer

Answer:
53,760,970 households/year
Step-by-step explanation:
First step is to do 65,929,420 - 12,168,450 = 53,760,970
Now divide 53,760,970 by 20 since the difference in 1997 and 1977 is 20
53,760,970/20 = 2,688,048.5
So each year 2,688,048.5 people got cable.
But it would be 53,760,970/year because then you could divide it by how ever many years to see how many people got cable.
Hope this helps!!
