Asked by help!! me

A television set is 36 inches wide and has a diagonal length of 42 inches. To the nearest inch, how tall is the set?
A.9
B.13
C.22
D.55
Is the answer D?
Answered by Brady
Is this calling for the Pythagorean Theorem equation? If so, D must be correct.
Answered by Ms. Sue
No.
Use the Pythagorean Theorem.

The diagonal is the hypotenuse.

Answered by Brady
Ignore me, I made a mistake in doing the math. Ms. Sue is correct.
Answered by help!! me
Yes Brady or is. I did 36^2+42^2=3060 √3060=55.317 so D would be the answer right?
Answered by Brady
That's what I did the first time, but on the second time I got a higher number, and messed up. However, I do agree with your answer of D.

Could the answer be C?
Answered by Brady
Yeah, it could be, I looked some things up, and it said 21.6 as the answer or close to 22. However, I don't know which answer is correct now. Sorry.
Answered by help!! me
The answer was C you helped me so much please help me more when you can Brady!! Thank you.
Answered by Brady
Yeah, I will help you when I can! :)

Its a 32 inch tv with a 25 inch widths. Whats the height?
Answered by Katie
The correct is c 22 trust me will pass it.

It can't be 55 inches. You're told that the diagonal, which is the hypotenuse of the right triangle, is 42 inches. The hypotenuse (side opposite the right angle) is ALWAYS the longest side in a right triangle, which eliminates 55 inches as a possible answer. Using the pythagorean theorem, the answer is the square root of 42 squared minus 36 squared, which is 21.6 inches, which rounds up to 22. By the way, modern TVs use a 16:9 aspect ratio (ratio of width to height), so for a width of 42 inches, a proportionate height should be 25 inches -- so the dimensions of this problem are slightly off.
Answered by John
THe aspect ratio, or ratio of screen width to height, is 16:9 for modern TVs. The diagonal is the hypotenuse in a right triangle, with the width and height as the other two legs. With this ratio and the pythagorean theorem, the width and height can be found when the diagonal size is known. a 25 inch diagonal screen has width of about 22 inches, and height of about 12 inches. a 50 inch screen will have width of about 44 inches, and height of almost 25 inches.

If the TV is 5” wider and 3” higher, what is the new diagonal measurement?

hey john thanks for giving me a strait answer like this usually i am a person that only speaks when a arguement happens so when something like "B IS RIGHT YOU ALL ARE DUMMASSES" i can help them because i go here not to use the information at hand but to help those in a arguement with them self's to see who is right and tell them the facts to make them understand what is Conexus but you gave me a big answer and well it was well proved i would say one thing is that the teachers aren't looking for its ratio don't know why but occasionally you will find answers that will be different then they are supposed to be and people usually argue over that because it seems like its one answer but then someone says something else and then people choose to agree but to me it just seems like two people changing their name to get a good argument with other people involved but thanks (NOT SAYING ITS CORRECT YET JUST SAYING THANKS FOR A GOOD EXPLAINATION)

ITS 22!! I have saved the day!!
Answered by Robert
It's not D, but C. If you use C to find the diagonal length it will work, but D won't. Watch this, I will use Pythagoras Theruom.
This is C. = √22²+36²= 42
This is D. = √55²+36²= 65.7
Your Welcome
