Answer: PQR=32
Step-by-step explanation:
RQS+PQR=PQS
(4x+4)+(3x-1)=80
7x+3=80
7x=77
x=11
PQR=(3x-1)=> (3(11)-1) => 33-1=32
I found this on Yahoo answers 18 different sets.
There are 6 faces, so that's 6 sets.
If we draw two parallel diagonals on two opposite faces, their endpoints are another set of four coplanar points. There are 3 pairs of opposite faces, and each has two such sets of diagonals, giving us another 6 sets.
Now consider the four diagonals of the cube. They all meet at a single point in the center of the cube. Therefore, any pair of them represent a pair of intersecting lines and so define a plane. So any pair of these diagonals produces yet another set of four coplanar vertices.
There are four such diagonals, and there are
4C2 = 4! / (2! 2!) = 4 * 3 / 2 = 6 different combinations comprised of two of them, so that's another 6.
That gives us a total of 18 different such sets of four coplanar vertices of the cube. No other combinations of four vertices are coplanar.
