Guys, I need help with this, really tickling my brain....

Put in a pic. of it.

Help please!

Those are really easy. Look in your book for information about corresponding, alternate interor, and alternate exterior angles.

I don't know how to solve the algebra...I need the answers, I have tutorial in like 1 hour, so yea, Im screwed.

I can't really tell you how to do it without helping you cheat.

Pretty please, I gotta leave in 45 min...hang on, can you like give me an outline?

ok, here's a hint (a BIG one): 3, 7, 1, and 5 are all the same...

2, 4, 6, and 8 are the same...

since you can easily get x from those two equations, (ANOTHER hint: 2x+40=3x+20 solve from there) you can then get 1, 3, 7, and 5. Subtract that measure from 180, because as you can see, any combination of two would lead to 180 degrees (like 5 and 6, 1 and 2, etc.)

do the same for the other equations, if the they end up being different (like in number two)

Exactly!
Solve for x.
2x+40=3x+20
If you donâ€™t know that, I guess I(and many others) could do that for you, but you only need pre-algebra for that, I learned it last yr. in pre-algebra (Iâ€™m in algebra this yr).

Then of course you fill in for x
2(whatever x is, I wonâ€™t tell you)+40
^For angle 1 or 5 or 7 or 3^
Then because you know that line has 180 degrees in it, just do this problem.
180-(angle1,3,5,or 7)
Then uâ€™ll find angle 2,4,6 or 8
Easy peasy (errâ€¦ since someone doesnâ€™t like that phrase, I forgot who)
Easyâ€¦ cheesy?
edit: it was wallydawg who hates that phrase

Gamelver helped a lot, yes I'm back, and I actually went on Benheck on my PSP right before class started. THANKS, to you, my PSP, and my PSPcalc homebrew app

im in 7th pre algabra and i could solve that

Hey, I'm studying little trigonemetry, Math B, already took my SAT's for Hopkins (got a combined score of 1120 btw) and did a bevy of things. I skipped all the easy 'crap' if you will, so yea, and I realized I had HW about an hour before class started, so you know, SONIC RUSh!

gotta go fast gotta go faster faster faster sonic x

Wow, ummm... why do I find it hard to believe you are in trig if you couldn't solve such a simple equation? That's basic algebra, my friend. Just one bit of advice; I wouldn't become a programmer if I were you

First trial of C++....I think I made people outside the room cry.

(< means Angle)

1. Equation: 2x+40 = 3x+20
x = 20
<1 = 80
<2 = 100
<3 = 80
<4 = 100
<5 = 80
<6 = 100
<7 = 80
<8 = 100

2. Equation: 3x+40+2x=180 (Consecutive Interior Angles)
x = 28
<1 = 56
<2 = 124
<3 = 56
<4 = 124
<5 = 56
<6 = 124
<7 = 56
<8 = 124

3. Don't even understand the question. What the hell is m<8 about equal to m<3?

Anyways, this is basic Geometry combined with Algebra 1. I just took a mid-term final on this crap today.

You're kinda late skyone

but thanks, also take into retrospect, that I'm just starting it.....
