Enzo drew Triangle K L N. In Enzo’s triangle, Measure of angle K is represented as x degrees. The measure of Angle L is 5 times
anygoal [31]

Answer:

Angle k = 14°,L = 70° and N = 96°

Step-by-step explanation:

According to the question,Enzo drew Triangle K L N. In Enzo’s triangle, Measure of angle K is represented as x degrees. The measure of Angle L is 5 times Measure of angle K. The measure of Angle N is 16 degrees less than 8 times Measure of angle K.

From here,we know that angles in a triangle sum up to 180°

If angle k = x

Angle L = 5x

And angle N = 8x - 16

Sum of a all three is equal to 180°

(8x - 16) + x + 5x = 180

14x -16 = 180

X = 196/14

X= 14.

Therefore,angles k = 14°, L = 70° and N= 96°

Let's now assume that the question was to find the angles k,l and n which is already written above and to pick the correct statement relating to the question.

My statement here is( since we weren't given the complete question) that the triangle is a scalene triangle

This Question is Incomplete

Complete Question

As an aid to the establishment of personnel requirements, the director of a hospital wishes to estimate the mean number of people who are admitted to the emergency room during a 24-hour period. The director randomly selects 64 different 24-hour periods and determines the number of admissions for each. For this sample, X = 396 and S = 100. Using the sample standard deviation as an estimate for the population standard deviation, what size sample should the director choose if she wishes to estimate the mean number of admissions per 24-hour period to within 1 admission with 99% reliability, what size sample should she choose?

Answer:

Sample size n = 16

Step-by-step explanation:

We use the formula for Margin of Error for the question

Margin of Error = z × Standard deviation/√n

Margin of Error = 1

z score for 99% confidence interval = 2.576

Standard deviation = 100

1 = 2.576 × 100/√n

1 × √n = 257.6

√n = 257.6/1

n = √257.6

n = 16.049922118

Approximately = 16

Therefore, the sample size = 16
