For y try substracting 112 from 180 wich should give u 60 which is y now add 60 plus 58 which is 118 now substract 118 from 180 which is 62 aka x
Using the z-distribution, a sample size of 180 is needed for the estimate.
<h3>What is a z-distribution confidence interval?</h3>
The confidence interval is:

The margin of error is given by:

In which:
is the sample mean.
is the standard deviation for the population.
In this problem, we have a 98% confidence level, hence
, z is the value of Z that has a p-value of
, so the critical value is z = 2.327.
The population standard deviation is of
, and to find the sample size, we have to solve for n when M = 4.
Hence:





n = 179.03.
Rounding up, as a sample size of 179 would result in an error slightly above 4, a sample of 180 is needed.

Pretty sure 6.5 because line CB and ZY are similar and you divide by 3 to make them similar so you divide line AB by 3 and you get 6.5
The answer is 78.5 you can get this by multiplying pi by the radius which is 5 then square it and you get 78.5
Answer:
I can't be quite specific without no protractor, but I will say it could be in-between 40 degrees and 20 degrees.
