@jim_thompson5910 You really helped last time :D Would you mind helping me again if you're not busy?

Which ones do you need help with?

So number 2. It is an isosceles triangle. Do you know what an isosceles triangle is?

Yes, a isosceles triangle is a triangle that has two equal sides and two equal angels.

That is very good. So what is the sum of all the angles of a triangle?

The sum of all the angles of a triangle is 180 degrees.

So why can't you get number 2?

Angle B is 35, angle C is 35 so you should be able to find angle A

Ohh, I'm sorry, I forgot to do that one, I do know how to do that one sorry! D:

So do you need help or not?

I do I'm sorry, my computer keeps freezing.

I don't really understand that theorem. @Mertsj

which question ?

I need all of the questions checked that have answers checked and then all of the questions that don't have yellow highlights I need help figuring out

If that is too cryptic, I am saying that angle 4 plus angle 2 add up to 180 degrees

for question 6
remember this:
|dw:1362333669480:dw|

Sorry, I didn't get a notification
For #3, is Angle 2 10?

Actually, it'd be 74. @phi

Which means Angle 1 is 106?

for question 3, you know angle 3 (64) and you know angle 2 (74)
angles 1,2 and 3 add to 180

Ohh okay, so Angle 1 is 42?

yes

question 7 is another "angles add upto 180 in a triangle)

I'm not sure how to solve that one :/

Did you get 6 ? Vertical angles are =

are the angles opposite each other when two lines cross

yes, so if you know angle 4 you know angle 2

Yes, but I can't seem to get the right answer for it. None of the answers would add up to 180

what is angle 2 ?
what is angle 3 ?

Angle 3 is 54, but I don't know what Angle 2 is, but it's the same as Angle 4

Didn't you answer question 5 ?

Yes but is that the right answer?

you can check: the 3 angles in the triangle add up to 180

I'll do some of the practice questions they have for me after I'm done my assignments. :D

Could you help me with the questions on Page 5 and the last page?

I just notice question 18 looks wrong.

Did I mix up Alternate Exterior Angles?

So would Angle 1 be the correct answer?

Ohh okay, I got mixed up because this is a different angle of the the diagram than I am used to :/

Does that mean Angle 6 and 7 are 140?

That's a good idea, I'll remembe that

25 looks wrong.

Well 3x = 6 would be 3x/3 = 6/3 right?

how do you get from
3x+5=11
to
3x = 6

Ohh you're right, that should be subtraction >.<

And then 26 would be E instead

yes

It's kinda confusing because it seems like they skipped a step

you mean for
3x+5=11 given
3x = 6 subtraction property
x = 2 division
what step is missing ?

The division property

True, with these I think I'll do the problem that way I know what's missing

For 28, I think it's C

No that's not right

Because 29 needs to be C

you are looking for the reason for changing M

I think 28 is Substitution

another rule out all the add and subtract properties which do not fit.
you are left with substitution, which makes sense. you are substituting 4n-6 for M

So now we have Addition, Subtraction, and Division left. 29 would be Addition?

how do you get from
4n-6=2n+46
to
2n -6= 46

...it'd be subtraction wouldn't it? They subtracted 2n from 4n?

If you have 2n's on the right side, you do you make it no n"s ?

if you have 2 apples and you take away 2 apples , how many apples do you have left ?

No apples left

and we call that ADD? SUBTRACT ? DIVIDE?

Subtracting

Yea, I'll practice these more too

almost done. question 30

Would that be C? Addition?

yes they added +6 to both sides
2n-6=46 becomes
2n - 6+ 6 = 46+6 addition property
2n = 52 simplify

And then finally 31 is E :D

yes, I think you got everything correct

now your teacher will think you are a genius and make you teach everybody else.

XDDD She'll be asking the wrong person :b

But some of us will know who the REAL genius is.!

O.o well yea

Thanks again Phi, I appreciate it! One of these days I'll be good at math!
