Question

Wayne's deli sells whole sandwiches and half sandwiches. The half sandwiches are in the shape of a triangle because they are cut diagonally. Wayne needs to order triangular-shaped containers for the half sandwiches, but he cannot find the file on his laptop that has the measurements.
Wayne believes the side lengths of the containers are 9 inches, 3 inches, and 5 inches. Could those be the correct measurements?

Answer 1

Answer:

No, those are not the correct measurements.

Step-by-step explanation:

Assuming that 9 will equal the hypotenuse we will use the Pythagorean theorem.

$a^2+b^2=c^2$

a = 5

b = 3

$5^2 + 3^2= 25 + 9 = 34$

Well $9^2= 81$

So...that doesn't quite work out.

Let's change our equation to double check.

$c^2/a^2= b^2$

$9^2/5^2 = b^2\\\\81/25 = 3.25$

Once again, that doesn't work out.

So  the final answer is, no. Those are not the correct measurements.
