The hardest easy geometry problem in the world... please help!

[Bioture]

I'm pulling my hair out over this... I can't seem to figure this out at all! And only elementary geometry is required, so I don't see how this works out! And the hints on the website do jack shit... now all I have is a bunch more lines in the triangle that doesn't lead anywhere.

please take a look. if you have the answer PM me so other people can suffer like I did first

Solving it, but I have to go right now. Pm'ing you what I have so far. I'll get back in a few hours to finish.

got it!


NO I don't I am stupid this is really hard

[Zeebu]

i think i have it

got 20

i had to draw a couple extra triangles and a circle

edit: i do this kinda stuff for fun sometimes... im a nerd like that

[cundor]

Took me 2 minutes

[Zeebu]

Took me 2 minutes

how?

how did you do it i mean

[Arikel]

Not that hard

Easy when you approach it methodically.

May be a small error here, but if angles are numbered from top to bottom once you get to :

D1 + E1 = 160
E2 + D2 = 130
D1 + D2 = 140
E1 + E2 = 150

You're quids in. You can then go :

D1 + E1 = D1 + D2 + 20
E1 = D2 + 20

And so on ...

It was really easy when I described angles in terms of x

Easy when you approach it methodically.

It's easy to do with geometry + simple algebra....but I think you're supposed to solve it with only geometry. (Stuff like 180 to a triangle or the line intersecting parallel lines thingy).

Oh, just geometry?

Well that's really simple too, i'll tell you guys when i get back from dinner

[Epinephrine]

I just stuffed random numbers into it, and it seemed to work. But since I was doing it all in my head, maybe it didn't

[Zeebu]

you guys that claim to get it so fast, how are you doing it?

it took me a while... i had to break out my compass =/

i dont think you can do it using only algebra

edit: if i can make it in paint (ugh) ill oput my solution up later

Ho:groovy: :groovy: :groovy:w long is your dinner?

We went to an old family friend's restaurant in Maryland

Here's a hint, lengths of sides on a triangle are proportional to the angle opposite them
