Question

The answer to this question Is beyond my knowledge can you explain

Answer 1

Because the paper is folded diagonally, you already know the two straight side lengths but not the diagonal. The triangle is a right triangle so you van use the Pythagorean Theorem to find the diagonal. The Pythagorean Theorem = a^2+b^2=c^2 so 8.5^2+8.5^2=144.5^2 144.5^2=12.02 The diagonal of the right triangle would then be 12.02 inches. Hope this helps!!

Answer 2

Pythagorean Theorem!


$a^{2}$+$b^{2}$=$c^{2}$
$8.5^{2}*8.5^{2}= c^{2}$
72.25+72.25=$c^{2}$
144.5=$c^{2}$
$\sqrt{144.5}$
12.02 or just 12
