The piece of paper measures 30.48cm (centimeters)
<h2>Why?</h2>We need to convert from inches to centimeters, we can do it using the following convertion factor:
Now, calculating we have:
Hence, we have that the piece of papers measures 30.48cm (centimeters)
Have a nice day!
but.... which is it? the + or the -? well, we know that tan(θ) > 0, is another way to say that the tangent of the angle is positive, now, for the tangent to be positive, since it's opposite/adjacent both opposite and adjacent have to be the same exact sign, now, we know the opposite is +2, so that means the adjacent has to be the same sign, thus is the positive version 3√(5)
thus
