Equations for 16:9 rectangle driven by diagonal dimension
Equations for 16:9 rectangle driven by diagonal dimension
(OP)
May be I'm being too quick on the trigger by posting this question here.
I'm trying to create a sketch of a rectangle that has a 16:9 ratio (yes, a widescreen, you guessed correctly). I want to add equations to the width and height to maintain the 16:9 ratio, but I want to the size of the rectangle to be driven by a diagonal dimension. Any suggestions?

To an Engineer, the glass is twice as big as it needs to be.

Since I'm NOT a SolidWorks user you'll have to figure out how these formulas would be formatted in order to define your 'sketch'.
Have fun

I suppose I could use the figures in JohnRBaker's spreadsheet to create equations between the sides' and the diagonal construction line's dimensions, but I think I'm going to stick with using the angle for now. Thanks to everyone for your help.

I'll challenge anyone to come-up with a simpler 'equation-based' solution than what I proposed. That being said, are you suggesting now that you're NOT interested in having the Diagonal distance as being the only variable? After all (from your initial post)...

Apply appropriate SW syntax to the above equation. Pat yourself on the back for being more "scientific".

I hope we all learned something from this thread because I think I may end up using the angular dimension solution after all. We paid so much for SolidWorks, might as well take advantage of its powerful tools.

h = 9 * d / sqrt(337)
That said, I would not use equations. I would draw small horizontal and vertical segments to make a small triangle with the diagonal to establish the slope for 16x9.

Draw the rectangle sides as line segments. Do 16 on the bottom, and 9 on the sides.
