## length of angled 2x4

Evening folks. This might be a dumb question so I apologize in advance. Anyhow im going to build a display stand for my wife and im trying to figure out how long a 2x4 cut at a 45 degree cute needs to be on both ends so that its sqauare to the ground. I want the overall height will be 34.5 inches. This is what i was talking about in case what i typed didnt make sense. Im assuming that those are 45. I dont have any plans so im just trying to copy the pic. Thanks for the help.

Ok i just remembered geometry 101. The Pythagorean theorem. If I did it right it should've right around 49 7/8in.

Simple and no math (this time).

As I sit here in my seat I saw a 4x8 sheet. I measured 34.5 up one way and then same square off the other. Pull a tape between the dots and there ya go.

Wouldn't that be a hair under 7/8"?

Not if you memorized your decimal equivalents as a kid.

After that, it is just geometry if you want to go with the 45 degree assumption.
 03-13-2014, 10:46 AM #12 Member   Join Date: Apr 2013 Posts: 39 Rewards Points: 25 The overall high will be 36 inches. I already subtracted the width of the top shelf. Probably should've mentioned earlier but the overall depth is going to be 36 inches as well Thanks for the help

Do you have a table that use that gives the diagonals! If so could you provide a length?

The conversions are still burned in my brain. Long before CM calculators they were it. You couldn't build much without them. I still use them to this day.

I prefer to sketch it out. If this is what you are planning, then the length is 48.79"
