Hi again! so vertical angles are angles that are across from eachother, so it would be 5 and 7 and 6 and 8
Answer:
and
are two such planes.
Step-by-step explanation:
To find the two planes whose intersection is the line
![x=6+3t\\ y=-8-3t\\ z=-1-t](https://tex.z-dn.net/?f=x%3D6%2B3t%5C%5C%20y%3D-8-3t%5C%5C%20z%3D-1-t)
You can say that <em>t</em> is equal to this expression
![t=\frac{x-6}{3} =\frac{y+8}{-3}=-z-1](https://tex.z-dn.net/?f=t%3D%5Cfrac%7Bx-6%7D%7B3%7D%20%3D%5Cfrac%7By%2B8%7D%7B-3%7D%3D-z-1)
Next,
![\frac{x-6}{3} =\frac{y+8}{-3}\\ \frac{y+8}{-3}=-z-1](https://tex.z-dn.net/?f=%5Cfrac%7Bx-6%7D%7B3%7D%20%3D%5Cfrac%7By%2B8%7D%7B-3%7D%5C%5C%20%5Cfrac%7By%2B8%7D%7B-3%7D%3D-z-1)
Then,
and
are two such planes.
You can see in the image attached that the intersection of this planes is the line
![x=6+3t\\ y=-8-3t\\ z=-1-t](https://tex.z-dn.net/?f=x%3D6%2B3t%5C%5C%20y%3D-8-3t%5C%5C%20z%3D-1-t)
Answer:
0.1875 and 0.12
Step-by-step explanation:
3/4x1/4 is 0.1875. 3/5 x 1/5 is 0.12
Answer:
Step-by-step explanation:
Perimeter is found by adding together all the lengths of the sides. For us, that is x + (2x + 5) + (6x - 17) + (3x + 2). Now we will just combine like terms. We can also drop the parenthesis because they do nothing for us and mean nothing to the problem.
x + 2x + 5 + 6x - 17 + 3x + 2 becomes
12x - 10
12/x=6/7 answer: x=14
6x/4=8/12 answer x = 0.4444444444
7/x+13=4/12 answer x=8
y+5/y=10/8 answer y=20
