Question

Does anyone know this

Answer 1

9.2

Explanation:

We can use the Pythagorean Theorem, a^2 + b^2 = c^2 to solve this. Since a and b are the lengths of the two sides and c is the length of the hypotenuse, we modify the original formula to c =
`\sqrt{a^(2) +b^(2) }` to find the length of the diagonal. We would get c =
`\sqrt{7^(2) +6^(2) }` = 9.2.
