Given :
The vertices of parallelogram ABCD are A(4,0,3), B(3,4,-2),C(-2,0,1).
To Find :
The coordinates of fourth vertices.
Solution :
We know, the vertices are ABCD .
Let, point D is (x,y,z) .
Also, diagonals of a parallelogram bisect each other.
Let, point of intersection of daigonal is O.
Coordinates of O are :
O(1,0,2)
Value of point O through BD.
Therefore, the fourth vertices is D( -1,-4,6 ).
Answer:
A) 8,500
B) B, C
Step-by-step explanation:
A) This seems to be a conversion problem. Since she runs 3 km every Monday Wednesday, and Friday, she would be running 6 km in total every week EXCLUDING the 2,500 meters. Since the question asks how many meters Kailee runs, you would need to convert 6 km to m and add the result to 2,500 meters. To convert km to m you just need to divide the value by 1000 (if your teacher asks for the full conversion method its 6 km * 1 m/1000 km or ), so 6 km is 6,000 meters. Adding 6,000 to the left over 2,500 from Saturday, the final answer will be 8,500.
B) For the second question, the answer are the two angles BELOW angle A (I'm guessing it is choice B and C). A right angle can be envisioned as a corner of a square or rectangle. The only angle which are larger (wider) are the angles below A (with the long hand pointing at 1 and the long hand pointing at 2).
