The intersection of two planes is a line.   That's not necessarily the definition of a line, but that's probably what they're looking for.


Answer: line

It can be defined as a line. If they don’t intersect it’s called parallel

Ignore the stuff around it ,could someone explain me this?
Ierofanga [76]

Answer:

The lines blue and green are perpendicular

Step-by-step explanation:

we know that

If two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes is -1)

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

step 1

Find the slope of the blue line

we have the points

(-1,-3) and (0,3)

substitute

m=\frac{3+3}{0+1}

m=\frac{6}{1}=6

step 2

Find the slope of the red line

we have the points

(3,-3) and (4,2)

substitute

m=\frac{2+3}{4-3}

m=\frac{5}{1}=5

step 3

Find the slope of the green line

we have the points

(-4,-1) and (2,-2)

substitute

m=\frac{-2+1}{2+4}

m=-\frac{1}{6}

step 4

Compare the slopes

Blue line ----> m=6

Red line ----. m=5

Green line ---> m=-\frac{1}{6}

so

The slope of the blue line and the green line are opposite reciprocal ( their product is equal to -1)

therefore

The lines blue and green are perpendicular

Find the length of side x in the simplest radical form with a rational denominator.
krok68 [10]

Answer:

\sqrt{2}

Step-by-step explanation:

We can use either angle, but I'm going to use the one on the bottom. So, in order to find x, we need to use tangent. One side we know is the adjacent, and the side we don't know is the opposite, therefore we need tangent. Here's the equation:

tan(45)=\frac{x}{\sqrt{2}}

Obviously, we can't have a root in our denominator, so we need to get rid of it somehow. Here's how:

We multiply the denominator of the fraction by \sqrt{2}. \sqrt{2} multiplied by itself is simply 2. Try it! We also want to multiply the numerator by \sqrt{2}, but there isn't really a number we can use with that, so we'll just add it to the side. The equation you have now is:

tan(45)=\frac{x\sqrt{2} }{2}

Let's try to work this out now. Since the denominator is 2, we have to multiply both sides by it to find x.

\frac{x\sqrt{2} }{2*2} =x\sqrt{2}

tan(45)*2=2

We can plug 2 in for the x in the numerator now:

\frac{2\sqrt{2} }{2}

2 and 2 cancel out, so you get 1 in both the numerator and denominator. That's how we get our answer of x=\sqrt{2}

Also, because this is a 45-45-90 triangle, you don't really have to do all that work. If it's a 45-45-90 triangle, both legs should be the same length. :)
