Since consecutive angles of parallelograms are supplementary (they add the equal 180 degrees), you can set up the following equation to solve:

5x - 2 + 3x + 10 = 180
8x + 8 = 180
8x = 172
x = 21.5

Now let’s check our work:

5(21.5) - 2 + 3(21.5) + 10 = 180
107.5 - 2 + 64.5 + 10 = 180
180 = 180

The answer:
x = 21.5

Hope this helps.

Find two different planes whose intersection is theline:x = 6 + 3ty = -8 - 3tz = -1 - tWrite equations for each plane in the for

alina1380 [7]

Answer:

$x+y=-2$ and $3z-y=5$ are two such planes.

Step-by-step explanation:

To find the two planes whose intersection is the line

$x=6+3t\\ y=-8-3t\\ z=-1-t$

You can say that <em>t</em> is equal to this expression

$t=\frac{x-6}{3} =\frac{y+8}{-3}=-z-1$

Next,

$\frac{x-6}{3} =\frac{y+8}{-3}\\ \frac{y+8}{-3}=-z-1$

Then,

$x+y=-2$ and $3z-y=5$ are two such planes.

You can see in the image attached that the intersection of this planes is the line

$x=6+3t\\ y=-8-3t\\ z=-1-t$
