Answer 2

"Is" is the correct answer. The top and bottom lines are indeed parallel, and the two connecting lines are the same length :)

Answer 3

Okie, how about this one? http://prntscr.com/hiyzo4

Answer 4

I believe it's 8 units, but I could be wrong

Answer 5

Okie

Answer 6

Thanks,

Answer 7

You're welcome ^.^

Answer 8

Can you help me with some more? http://prntscr.com/hiz73e

Answer 9

Yeah!
For this next one, you can see that J is a right angle, which means it's 90 degrees
so that means 5x is equal to 90.
divide both sides by 5 and you figure out x is 18
then you plug 18 in 3x to find out what angle L is.
You try it ;D

Answer 10

Remember that a triangle has a total of 180 degrees when each angles is added up.

\(\large\bf{5x+3x+2x=180}\)

Combine like terms.

\(\large\bf{10x=180}\)

Divide by 10 to find x.

\(\bf\large\bf{\frac{10x}{10}=\frac{180}{10}}\)

Plug x for L .

Answer 11

Okie, I'll give it a shot

Answer 12

@563blackghost will it always equal 180?

Answer 13

For triangles it will ALWAYS be 180 degrees.

Answer 14

Ahh okay, so let me see if I got this

Answer 16

They would all equal 180 and then I just continue from there?

Answer 17

You are only given an interior angle equal to 75 degrees, and an exterior angle of 140 degrees.

Exterior angles are located outside of the shape.

Since JLM lies on a straight line this means that JLM and JLK are supplementary angles (that equal to 180 degrees). So we subtract `180 - 140` equals to `40` so `40 = JKL`.

Now we know of 2 angles for the triangle. Now to find the third angle we need to add the known angles `40 and 75` and subtract it with 180` to find `KJL`.

Answer 18

That equal 65

Answer 19

Yep

Answer 20

So 65 would be it? Or we Subtract that from both sides?

Answer 21

Sorry, I'm dumb for this. Its all confusing at first XD

Answer 22

It would be 65.

\(\bf{75 + 40 + 65 = 180}\)

Answer 23

Ahhh

Answer 24

Make sure to add the angles to see if you are right ;)

Answer 25

Which angles?

Answer 26

The angles that are in the shape.

Not the ones outside of the shape those are exterior.

Answer 27

Oh okay. So to put it all in one, you subtract the angle numbers by 180 and then subtract from both sides?

Answer 28

If you are trying to identify x `(such as given that the angles are 3x 5x, 6x)` Then you would add them and then divide each side by the number being multiplied with 180 `(since a triangle's angles equal to 180)`.

Subtracting only comes in when you are trying to find the last angle. This is where we know of two angles and the total angle (180) but not the third. So we would add the two angles and then subtract by 180 degrees to get the last angle.

Answer 29

Ahh okay, makes sense. I guess I will try one and you can let me know if I'm right or not

Answer 30

ok

Answer 31

Am I good so far? http://prntscr.com/hizpxl

Answer 32

First analyze which kind of triangle it is. Based on the sides what kind is it?

Answer 33

I think its Quadrilateral

Answer 34

Quadrilaterals deal with shapes that have 4 sides.

Look at this:

Answer 35

Close

Answer 36

The triangle in the problem is an equilateral. This means that each angle is 60 degrees.

So...

\(\large\bf{8y-4=60}\)

Add 4 to each side.

\(\large\bf{8y=64}\)

What is y?

Answer 37

http://prntscr.com/hizymu Am I right?

Answer 38

And y=8

Answer 39

y does equal 8.

The equation is kept as \(\bf{3x-3}\).

\(\large\bf{3x-3=60}\)

Add 3 from each side.

\(\large\bf{3x=63}\)

Now you divide by 3 on both sides to get x.

Answer 40

Ohhh if I were looking for x, then it'd be 21

Answer 41

For division

Answer 42

yea its 21

Answer 43

Okie, I think I got this. Thanks :)

Answer 44

Wish I can choose you as well for the best response
