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

is ther is a picture with this question

No, sorry

ok are these angles equal?

Uhm...I don't know

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

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

ok

draw it

The question? I'm not sure how to

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

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

And that's all the information I have on it

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

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

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

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

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.

what does it say above the question?

It's another question asking to name an alterior angle

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

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

It doesn't have to be good.

I will attach it

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

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

so the angle must be 60

Ohh. Okay. Thank you so much!

no problem do you understand how I did that?

No can you explain it?

Yes =)

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

Yes

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)

each other**

A little

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?

Ohh, yes, I do.

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?

Yes, I get it

awesome =)

Thank you so much! I appreciate all your help

no problem dude =)
