As you can see, we can solve the missing side of a right triangle using

In our problem, we have a diagonal (hypotenuse) of

In the Pythagorean Theorem, that means we have

So let's plug them into the formula:

Simplify by squaring:

Subtract

Square root both sides:

Therefore, **the width of the monitor screen is #sqrt115# inches or about #10.724# inches (rounded to the nearest thousandth's place).**
