congruent angles are of similar measures

congruent angles that are congruent to ∠7:

∠6 ( vertically opposite angles )

∠3 ( corresponding angles )

∠2 ( alternate interior angles )

See how

<7+<5 are linear pairs
<5+<3 are also linear pairs

From both

<7 and <3 are equal(Corresponding angles)

Similarly

<7 nd <6 are equal (Opposite angles)

And

<6 and <2 are corresponding and equal so

<7 and <2 are equal

How do i solve systems of equations by elimination?

Vera_Pavlovna [14]

Say you had this problem:

-4x - 2y= -12
4x +8y = -24

First you would have to cancel out one part of the equation to get on variable alone. In this case it's easy it would be -4x and 4x. So then you would cancel those out.

Now we have

-2y= -12
8y =-24

so then you just add them all up

6y=-36

Next you just divide both sides by 6
so then you answer for y would be -6.

Next you would choose one of your equations and plug the -6 in.

So it would be

-4x -2 (-6) =-24

So you would times negative 2 by negative 6, which would be positive 12. Since a negative times a negative equales a positive.

-4x + 12= -24

Next you would minus 12 on both sides.

-4x + 12=-24
- 12 = -12

The 12's would cancel out and then you just minus -24 by -12 which you would ended up just plusing them together because a negative plus a negative equales a negative. Or a negative minus a negative number would end up adding them up.

-4x= -36

Next you would get x alone and how you would do that is you would divide -4 in both sides which would cancel them -4 out then it would be divided by -36.

So it would look like this.

-4x= -36
-4 -4

So negative 36 divided by negative 4 is 9.

So your final answer would be

y= -6
x= 9

I hope I explained to you properly how to do systems of equations by elimination.

Simplify square root of -36 a. 6i b. -6i c. 6 d. -6

inysia [295]

Answer:

A. 6i

Step-by-step explanation:

Apply by the radicial rule.

$\sqrt{-36}=\sqrt{-1}\sqrt{36}$

$\sqrt{-1}\sqrt{36}$

Imaginary number.

$\sqrt{36 i}$

Square root the numbers from left to right.

$6^2=36$

$\sqrt{6^2}=6$

6i is the correct answer.

I hope this helps you, and have a wonderful day.

How to determine if the line is parallel , perpendicular, or neither

4vir4ik [10]

It is parallel if the lines are in straight line next to each other, but don't cross.
It is perpendicular if these lines intersect to form right angles.
Neither if they don' t follow these rules
