Question

If m∠4 = (3x)° and m∠8 = (x + 40)°, what is the measure of ∠4?

Answer 1

is ther is a picture with this question

Answer 2

No, sorry

Answer 3

ok are these angles equal?

Answer 4

Uhm...I don't know

Answer 5

is that a hw question
i mean is there is a source with u like the lesson before that question that can help give more info to this question

Answer 6

Yes it's a homework question. The lesson was "angle relationships and parallel lines". I can't link, sorry. :(

Answer 7

ok

Answer 8

draw it

Answer 9

The question? I'm not sure how to

Answer 10

see the 3 blue buttons below the place where you type text

Answer 11

Oh I know, but I mean I'm not sure how to draw out the question

Answer 12

And that's all the information I have on it

Answer 13

We just need to see the relationship the angles have to each other in order to solve the problem

Answer 14

u mean it is a plain question with no picture involved above or under it that can help u in solving the problem

Answer 15

just look at the diagram in the problem and give a basic representation

Answer 16

you can't solve the problem without knowing how the angles are related

Answer 17

Yeah, there is no picture. I don't know how to represent it or how to figure out if the angles are related or not.

Answer 18

what does it say above the question?

Answer 19

It's another question asking to name an alterior angle

Answer 20

It has a picture. I'm not sure that they're related though.

Answer 21

no they for sure are related just need to know how. try to draw the picture.

Answer 22

It doesn't have to be good.

Answer 23

I will attach it

Answer 24

okay so angle 4 and 8 have the same value so set them equal to each other and solve for x

Answer 25

3x=x+40 then you get 2x=40 so x=20

Answer 26

so the angle must be 60

Answer 27

Ohh. Okay. Thank you so much!

Answer 28

no problem do you understand how I did that?

Answer 29

No can you explain it?

Answer 30

Yes =)

Answer 31

okay can you tell that angle 4 and 8 must have the same value?

Answer 32

Yes

Answer 33

okay so if they have the same value and you have the equations that represent that value for each of them then those equations have to be equal to each understand? (If not say so I will explain more)

Answer 34

each other**

Answer 35

A little

Answer 36

alright so think about it like this now that you know each angle equals 60 imagine 60 next to each of the equations. So 60=3x and 60=x+40. Now since they both equal the same value then you can also say 3x=x+40. Follow so far?

Answer 37

Ohh, yes, I do.

Answer 38

alright =) so replace that 60 with another variable because we don't know the value at the beginning of the question. So angle = 3x angle =x+40 then we need to find x in order to find the answer and we do that by setting the equations equal to eachother and then solving for x. Once we solve for x we can plug it back into one of the equations to get our value for angle. know what I mean?

Answer 39

Yes, I get it

Answer 40

awesome =)

Answer 41

Thank you so much! I appreciate all your help

Answer 42

no problem dude =)
