Question

Find the length of the hypotenuse round to the nearest hundredth

Answer 1

`\displaystyle 4√(5)`

Explanation:

Use the Pythagorean Theorem:

`\displaystyle a^2 + b^2 = c^2 \\ \\ 8^2 + 4^2 = c^2; √(80) = √(c^2) \\ \\ 4√(5)\:[or\:8,94427191...] = b`

So, you have this:

`\displaystyle 8,94 ≈ c`
