Agree. 14.25' if your 80 degree really start at 8'. From your pic, it looks like you are starting somewhere less than 8'. Easy way to remember .

Oscar Had A Heap Of Apples

O (pposite)
- = Sine ( Sine 10 degrees = 0.1736) x 18' = 3.1257 x 2 + 8 = 14.25'
H (ypotenuse)

A (djacent)
- = Cosine ( Cosine 80 degrees = 0.1736) x 18' = 3.1257 x 2 + 8 = 14.25'
H

O
- = Tan
A

You can flip it over to get Cotan, Sec, Csc

What happened to good old 2+2 I tried to google this equation and Google sent me to NASA's website y'all must be some pretty smart fellers.. Or maybe I'm... We'll never mind.

Too funny fellas....thanks again...this equation was too much for an ol Firefighter to figure out!!

I still remember Ms. Peterson in High School Geometry, "Some old hag, came around here, taking our apples."

Your sketch doesn't give all the info, if it's correct.
How far is each leg set "in" at the top?

If they are 8' at the top, then the bottom would be 14'-3 1/64".
If say they were set in, you need to subtract that from ^^^^ number.

I'm struggling with the 80degrees? 80 degrees is almost completely horizonal. What am I missing?

It spreads out quite a bit, when you figure in the 18' height.
Actually, 3' wider in each direction.

Yep, the longer the leg, the larger the deviation from perpendicular.

[Triple 7]

Here is how I do it. I put the legs on then measure it. Then I make another run to the metal shop since I didn't plan on the right amount of metal.

Hmmmm....what about the spread in the other direction? I'm assuming that you will be 10 degrees in that direction as well? If so, do a little more math to come up with the real "footprint".

It doesn't change the dimensions. You're just working it in two directions.

[helim83]

Yup

[Nado]

I cant see the pic, I got a little broken thumnail is all I see. What is the equation?

[Monark]

So this where the nerds hang out!

Hey, I resemble that remark.

Lol I like "some old hippie caught another hippie tripping on acid" [emoji23] lol always made me laugh.

I like. Learned a new one today.
