<h2>
Hello!</h2>
The answer is: 2
<h2>
Why?</h2>
Before solving the problem, we must remember the following:

So, for tan(45°) we have:

Also, for sin(30°), we have:

Then, substituting and dividing, we have:

So, the answer is 2.
Have a nice day!
The z-score is calculated as (x - m) / s, where x is the actual score, m is the mean, and s is the standard deviation. In this case, x = 176, m = 154, and s = 9.8. Therefore z can be calculated as: z = (176 - 154) / 9.8 = 2.245, and the z-score of 2.245 means that 176 is 2.245 standard deviations above the mean.
I did all the calculations and n would have to be 9 I promise
Answer:
x²+y²=225
Step-by-step explanation:
when centered at the origin the equation of a circle is x²+y²=r²
we are given x and y so 9²+12²=r²
