Two vertical poles have heights 6 ft. and 12 ft. A rope is attached from the top of each pole to the bottom of the other. How far above the ground do the ropes cross?

RE: Urgent! Need help or will fail Geometry!
Your problem is impossible to solve without knowing how far apart the poles are.I watched clouds awobbly from the floor o' that kayak. Souls cross ages like clouds cross skies, an' tho' a cloud's shape nor hue nor size don't stay the same, it's still a cloud an' so is a soul. Who can say where the cloud's blowed from or who the soul'll be 'morrow? Only Sonmi the east an' the west an' the compass an' the atlas, yay, only the atlas o' clouds.Comment

RE: Urgent! Need help or will fail Geometry!
Somehow I think we need to know how spaced out the poles are.
In any event, doing this in the lamest way possible, the result from drawing it in Paint says 4.2 feet. Then again, I have no idea how many feet were between the poles I used.

Nope, distance between poles doesn't matter.
I can solve it algebraically, or by cheating with graph paper XD but I've forgotten how to do this the geometric way.
The answer is 4 ft.♪~

RE: Urgent! Need help or will fail Geometry!
Oh, you're right. I was doing it graphically and kept getting different x values, but y would be the same every time because the functions change at the positions of the poles do.
Duh. ._.I watched clouds awobbly from the floor o' that kayak.

Hehehe.
Okay, I think I've gotten it the way your teacher probably wants you to know it.
Because distance doesn't matter, let's just say it's 1 to be easy.
So it looks like this:
We are looking for h.
Notice how h forms triangles that are similar to the triangles made by the poles: triangle ACF is similar to ADE, and ECF is similar to EBA.
Knowing this, we can use tangent ratios to solve. tangent(angle) = opp.side / adj.side
tan(x) = h / AF
tan(x) = 6 / 1
Solve between those, and you get h = 6*AF.
Now... other triangle!
tan(z) = h / FE (Fire Emblem lololol)
tan(z) = 12 / 1
Solve between those to get h = 12*FE.
Now look at our two equasions for h.
h = 6*AF
h = 12*FE
We know AF + FE = 1.
So AF = 1 - FE
Substitute...
6*(1 - FE) = 12*FE
Solve and we get FE = 1/3.
Substitute into h equasion...
h = 12*(1/3)
So finally,
h = 4.
Phew.
Mm, geometry.♪~

Oh.
See, as soon as you use trig functions, I go "what"
I never took Trig. It makes Calculus very fun.

Ouch =x
Trig/precalc was the time everything all started to click for me. It's confusing as heck at first, but once you get a grasp on what it's all about, it's like you've become enlightened on mathematics and everything finally makes sense all together. XD At least that's how it was for me.
Although I always did like geometry for some reason. Playing with spacial math is yummy fun.
The way you use trig ratios in geometry is pretty easy. It doesn't go into all the confusing stuff with sin waves and all that. All you need to know for geometry is the ratio for each ("SOH CAH TOA"). It's more handy than hard. =D
Gah. I dunno why I'm so blabbery about math right now... I must be craving it since I haven't had a single math course all year >_>♪~

omg shut up plz
I'm back in CS this year. I swear I won't ask you for help since it's just more material you can use in a0 chats or with Moogster.
