Answer: choice B
Explanation: Go through each answer choice and try the Pythagorean theorem to see if it works. This is because a right triangle’s side lengths are described by the Pythagorean theorem. one side^2 + second side^2 = longest side^2. In a right triangle, this equation will be true. Let me show you what I mean
For answer choice A:
(root 2)^2 + (root 3)^2 = (root 4)^2
2 + 3 = 4
5 = 4
5 does not equal 4. Therefore it cannot be A.
For answer choice B:
(root 8)^2 + (3)^2 = (root 17)^2
8 + 9 = 17
17 = 17
this is true! therefore this is a right triangle and it’s B

Hello!</h2>
The answer is: The population age 12 or under was 3680.
<h2>
Why?</h2>
If in 2010 the population of Kignsford was 8000, and by 2014 the population had increased by 15% we need to calculate the total population and then, calculate how many people was age 12 or under.
We must remember that we cannot work with percentage values, so, to make 15% a real number, we need to divide it by 100:
![15(Percentage)=\frac{15}{100}=0.15](https://tex.z-dn.net/?f=15%28Percentage%29%3D%5Cfrac%7B15%7D%7B100%7D%3D0.15)
So,
Calculating the population by 2014, we have:
![Population_{2014}=Population_{2010}+ Population_{2010}*0.15](https://tex.z-dn.net/?f=Population_%7B2014%7D%3DPopulation_%7B2010%7D%2B%20Population_%7B2010%7D%2A0.15)
Then, substituting we have:
![Population_{2014}=8000+ 8000*0.15=9200](https://tex.z-dn.net/?f=Population_%7B2014%7D%3D8000%2B%208000%2A0.15%3D9200)
Now, calculating the population that was age 12 or under, knowing that it was 2/5 of the total population, we have:
![Population=TotalPopulation*\frac{2}{5}\\\\Population=9200*\frac{2}{5}=3680](https://tex.z-dn.net/?f=Population%3DTotalPopulation%2A%5Cfrac%7B2%7D%7B5%7D%5C%5C%5C%5CPopulation%3D9200%2A%5Cfrac%7B2%7D%7B5%7D%3D3680)
So, the population age 12 or under was 3680.
Have a nice day!
Answer: n*4512 is less than or equal to 117
Step-by-step explanation: n=number N*45=X X=Number more than 117. X decreased by 12 is less than or equal to 117.

Answer:
The answer is obtuse
Step-by-step explanation:
because a triangle cannot be a right or parallel or a Isosceles.
Hope this helps!:)
