Question

joey made a sandwich that was 2 inches long and 4 inches high . if he cuts the sandwhich in half , what would be the diagonal length of the sandwhich?​

Answer 1

4.47 or 2√5

Explanation:

Cutting the sandwich in half will create 2 right triangles. The longest side, the diagonal, called the hypotenuse is found using the Pythagorean Theorem.

The sides of the right triangle will be 2, 4, and c.

`a^2+b^2=c^2\\2^2 + 4^2 = c^2\\4 + 16 = c^2\\20 = c^2\\√(20) = c\\2√(5) = c\\4.47 = c`
