Hey math ppl, solve for X

[Steve]

Is this enough info? Basically trying to find out the length of the long side.

http://www.wolframalpha.com/input/?i=36%5E2+(9x)^2=(16x)^2

And the answer is 36/(5sqrt(7)) which is about 2.72134

 

[busydude]

Use Pythagorean Theorem.

43.54"

 

[Steve]

Interesting, thank you. My parents have an entertainment cabinet which is 36" wide. Right now they have a 32" TV and I wanted to see how big a TV would fit in there. 16x2.72134 comes to 43.5" - but there's no accounting for bezel size. I figured maybe a 37" would fit at most but it seems like that size isn't being made any more. Now it seems like maybe a 40" would fit.

 

[KLin]

Dimensions of TV's always include bezel size that are listed on sites like amazon, crutchfield, etc. You're overanalyzing this.

 

[Krazy4Real]

geez... used to be able to do this in my sleep. I've been out of math for a long time.

 

[Steve]

You sure about that? I always thought the listed size was the screen size alone.

 

[IronWing]

This is like so 2005.

No... you can see the overall dimensions in product description/specifications.

The '42" Class Blah Blah' is screen size, but in every product page I've seen they give full dimensions including bezel and stand.

 

[KLin]

I'm not talking about the product name. I'm talking about in the specifications listed for the TV. They'll list the width,height and length of the TV.

 

[Bulk Beef]

You're overanalyzing this.

What he said.

 

[Steve]

Well in any case it seems like a 37" is the biggest that will fit, bezel included. Gonna have to measure a second time if I feel like pulling the trigger.

 

[Leros]

In the days of giant LCDs, entertainment cabinets don't really make sense anymore. People either hang them on the wall or get some kind of television stand.

 

[Steve]

I agree! I'm hoping someday they'll figure out a better setup. But you know, baby steps. Meanwhile I'll continue enjoying my 42" LCD unless something in my BF HDTVs thread catches my eye

 

[BoomerD]

We had an old-style entertainment center that was made to hold a 27" CRT television.
I cut it down to make a nice stand for the 50" plasma.
Not exactly ideal...as I lost some doors and shelves, but it still holds my stereo gear, blu-ray player, and cable box...plus a couple of cabinets (with doors) to hold misc. gear.

I was actually surprised at how well it worked.

 

[Steve]

That's actually not a bad idea...

 

[halik]

Umm 16x9 is the ratio of the long side to the short side, not the diagonal...

Yep, that cabinet will hold a TV that is 36 in. (width) by 20.25 in. (height) or 41.30 in. diagonal.

EDIT: Diagonal value for a 16:9 TV

 

[olds]

this is like so 2005.

damn you!

Your boy friend has a HDTV thread? Link?

Not enough info without knowing if one of the angles is a right angle.

 

[eits]

a^2 + b^2 = c^2

(36)^2 + (9x)^2 = (16x)^2

1296 + 81x^2 = 256x^2

1296 = 175x^2

x^2 = 7.406

x = 2.72
