The three vectors
,
, and
each terminate on the plane. We can get two vectors that lie on the plane itself (or rather, point in the same direction as vectors that do lie on the plane) by taking the vector difference of any two of these. For instance,


Then the cross product of these two results is normal to the plane:

Let
be a point on the plane. Then the vector connecting
to a known point on the plane, say (0, 0, 1), is orthogonal to the normal vector above, so that

which reduces to the equation of the plane,

Let
. Then the volume of the region above
and below the plane is

The answer is F
I hope I helped. Brainliest would be appreciated.
-$69.68 is your answer if I hope that this is correct.
Answer:

Step-by-step explanation:
The ratio of the same side interior angles of two parallel lines is 33:3
If two parallel lines are cut by a transversal
Sum of the same side interior angles = 180 degrees.
Therefore, the two same-side interior angles are:

We can then say that the measure of all eight angles formed by the parallel lines and transversal starting from the upper left in a clockwise rotation is:
Answer:
C
Step-by-step explanation:
do that with pithagoras:
20² + 4,5² = x²
400 + 20,25 = x²
420,25 = x²
x = 
x ~ 20,5
