We know all the side lengths so can use law of cosines. a=90, b=55, and c=50.
2500=8100+3025-2(90)(55)cos(C)
cos(C)=.8712
C=arccos(.8712)=29.4 degrees
Using proportions, it is found that the correct statement is:
D. The number of visitors who prefer camping will be 2 times the number of visitors who prefer water sports.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount.
In this problem, the table is from a sample of 80 visitors.
Since the <u>proportions stay the same</u>, just the number of visitors change, the correct statement is given by:
D. The number of visitors who prefer camping will be 2 times the number of visitors who prefer water sports.
As from the 80 students, 28 prefer camping and 14 prefer water sports, hence from 200, these numbers will be of 70 and 35 respectively.

Hello.
Numbers with | | around them are the absolute value, meaning it is always positive.
|-1.43| and |-1.21| become 1.43 and 1.21
The equation is now 1.43 - 7.1 + 1.21
Solve.
1.43 - 7.1 + 1.21
-5.67 + 1.21
-4.46
-4.46 is the final answer.
