Simplify the expression. (1-cot(x))^2/cot(x)
a) cot(x)+2
b) sin(x) c0s(x)-2
c)tan(x)+cot(x)-2
d)csc^3(x) cot(x)-1

I've got this as my ans but I'm not sure thoughh so I think the ans is A

12.4%

Step-by-step explanation:

The results from the random sample counts 124 from a total of 1000 people that wear contact lenses. This means is the percentageof the people in the sample that wear contact lenses.Because it is a random sample, it is suppose to reflect the behavior of the total population. Then we can expect or predict  similar percentage of Americans wearing contact lenses (12.4%).
