Our forests are 'kept in check' by using controlled fires. When our wild areas can be destroyed. Native plants and animals are pushed out of their homes to not go back for years. Certain aspects of the forest can take up to sixty-five years to regenerate. While this may not seem long to the universe, this can be a life time for us. Yes our forests need fire, but they can do it themselves. Before people came along our wilderness was keeping itself in control for millions of years. But now humans step in and believe that they need to take over everything. We are already cutting down forests for trees and unnecessary housing. So why do we need to get rid of it more? Fires can handle themselves. Forests know what they are doing. But do we?
Answer:
The possible coordinates for R are contained in the following expression:
Explanation:
From statement we notice that line segment PQ is parallel to x-axis and by Geometry we know that an equilateral triangles have three side with equal length and three angles of 60°. In consequence, the height of the triangle is parallel to the y-axis and the possible coordinates for point R are contained in this equation:
(1)
Where:
, 
- Coordinates of the midpoint of the line segment PQ.
- Side length of the line segment PQ.
The length of the line segment PQ is determined by the Pythagorean Theorem:
(2)
If we know that 
and 
, then the length of the line segment PQ is:
![l_{PQ} = \sqrt{[-2-(-9)]^{2}+[(-2)-(-2)]^{2}}](https://tex.z-dn.net/?f=l_%7BPQ%7D%20%3D%20%5Csqrt%7B%5B-2-%28-9%29%5D%5E%7B2%7D%2B%5B%28-2%29-%28-2%29%5D%5E%7B2%7D%7D)
And the coordinates of the midpoint are, respectively:
Lastly, the possible coordinates of vertex R are, respectively:
The answer is E because it has the right grammar
