Hey there!!
The total number of angles are 5 and the total sum of angles in a 5 sided shape is 540°
The angles given are :
107, 144, 130,x and 90
If we add them up, we get 540
Hence,
107+144+130+x+90 = 540
471 + x = 540
x = 69°
Hope my answer helps!!

Answer:
d. The width of Elly's interval will be less than the width of Drew's interval.
Step-by-step explanation:
The confidence level and the width of the confidence interval are direct proportional. This means that a confidence interval with a higher confidence level has a higher width.
For example, a 99 percent confidence interval is wider than a 90 percent confidence interval.
The midpoint of the confidence interval is the mean of the population, no matter the confidence level.
In this problem, we have that:
Elly: 90 percent CI
Drew: 99 percent CI
The correct answer is:
d. The width of Elly's interval will be less than the width of Drew's interval.
