Okay, the external lines form up to become a perfect Pentagon. You are to find the dimensions asked for. A is given as 200kilometers.

ugh is this uni stuff? I figure it has to go along with breaking it down with pythagorean theorem but probably not now that I look at it more. I think J equals 6000km2 the 2 is squared e=108

Ah the golden ratio. Simple problem really, but I don't have a scientific calculator on me and no way I'm spending time on this cuz I hate math.

There are scientific calculators online http://ostermiller.org/calc/calculator.html noone has the skill?

Oh I know how to do this, actually very easy (I like geometry!). Lots of pthagorean therom and sin cos tan stuff! ...but my quackulator died so I will do it once I can get new batteries. Not to mention it is like 6am, and I am running off 2 hours of sleep. Me: Ok time to do some trigonometry! Brain: Trig? Oh no you don't! You did not give me enough sleep! Now where is that "dumb blonde" button... ah! *push* :bump2: Me: ok so its sin(108/3......) ...errrrrrrpplllhhhhh... OH LOOK! SHINY OBJECT!!! YAY!!!!1! *runs across room* :bounce:

WARNING!! SPOILER BELOW!! A=200 B=323.6 C=123.0 D=76.0 E=29.0 F=161.7 (these are in degrees) G=36 H=108 I=72 J=68819.1 Like I said, I'm a math geek.

Here's one: An army jeep left its base at 12 noon for a destination 300 miles distant across a flat terrain. The jeeps average rate the first hour was 40 mph, during the second hour 45 mph, during the third 50 mph, ect. At 1:40 pm, a helicopter, traveling at a uniform rate of 75 mph, set out to over take the jeep. At what time did the helicopter reach the jeep?

Convert the shit to real units and I might try to solve it *mumbles about stupid people using stupid units*

units don't matter, :mno: you'd get the same answer if you convert all the distances to km, and all speeds to kmph.

250 miles out at 5 PM I would guess, given constant directions. edit to add given no time change zones were crossed.

Of course, if the jeep stopped to take a bathroom break.........:hungry: or to eat......or both.... or....

The helicopter will reach the jeep at 5:00pm. The helicopter will reach the base at 5:40pm, the jeep will reach the base at ~5:46:09.23pm.

Eye level will be at 60 inches above sea level at each end. Location: on the ocean where nothing is between both sets of eyes Conditions: calm; no wind What is the greatest distance, in linear feet, one set of eyes can look toward the horizon and see the other set of eyes?

I hate math so I am not going to solve it with numbers, but this is how (I assume) you solve it. Figure out the curvature of the earth, and take a tangential point to the surface, and see how long out the line goes before it is 5 feet from the surface. Using sin, cos, and tan and all that good stuff. The radius of the earth could be related to the unit circle and scaled acordingly.
