Determine the dimensions of the screen of a 42-inch tv with a 4: 3 aspect ratio.
hint: use 3x^2+4x^2=42^2 to .

For this case, the first thing you should do is know that the measurement of a television is given by the diagonal of the television.

Therefore, to find the value of x, we use the Pythagorean theorem.

We have then:

Rewriting we have:

Then the dimensions are given by:

the dimensions of the screen are: 33.6* 25.2

4.08%

step-by-step explanation:

can you make your screen more see able?

then i might be able to .
