Answer and Step-by-step explanation:
90ft = a
55ft = b
50ft = c
Plug into equation.
![50^{2} = 90^{2} + 55^{2} - 2(90)(55)cosC\\\\2500 = 11125 - 9900(cosC)\\\\-8625 = -9900(cosC)\\\\0.8712 = cosC\\\\cos^{-1} (0.8712) = C\\\\29.4](https://tex.z-dn.net/?f=50%5E%7B2%7D%20%20%3D%2090%5E%7B2%7D%20%20%2B%2055%5E%7B2%7D%20%20-%202%2890%29%2855%29cosC%5C%5C%5C%5C2500%20%3D%2011125%20-%209900%28cosC%29%5C%5C%5C%5C-8625%20%3D%20-9900%28cosC%29%5C%5C%5C%5C0.8712%20%3D%20cosC%5C%5C%5C%5Ccos%5E%7B-1%7D%20%280.8712%29%20%3D%20C%5C%5C%5C%5C29.4)
29.4° is the answer.
The answers to the questions are:
1. The confidence level is 99 percent.
2. We have to conclude that there is no sufficient evidence available to support this claim because the Confidence interval contains 75 sec.
<h3>How to solve for the confidence level</h3>
1. The confidence level here should be
1- 0.01 = 0.99
= 99 percent
Given that, 99% confidence interval for population mean (μ) is (-34.1 sec u< u < 264.1 ) seconds.
We are to test the claim that the population mean is greater than 75 sec.
2.
The given confidence interval contains the value of 75 sec, so there is not sufficient evidence to support the claim that the mean is greater than 75 sec.
