We know that the trigonometric identity that uses the adjacent side and the hypotenuse is cosine. We can set this up as:

We need to solve for x, so let's isolate it:

So,
x = 10.2 units

Option C.
Step-by-step explanation:
Given information:
Sample size = 150
Number of Opinions = 3 (Yes, No, No Opinion)
Yes = 40
No = 60
No opinion = 50
We need to find the expected frequency for each group.
Expected frequency for each group is the quotient of sample size and number of opinions.



Therefore, the correct option is C.
