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:
Who is at the door? Who's belongings are these? Who is responsible for this great mess?
Answer:
After a parrotfish eats algae-covered coral, the coral travels through the fish's digestive system, and then it is deposited in the reef as white coral sand. Sentence that has one independent clause and no subordinate clauses.
