Answer 1

How to use the Pythagorean theorem:)

1. Input the two lengths that you have into the formula. ...
2. After the values are put into the formula we have 4²+ 8² = c²
3. Square each term to get 16 + 64 = c²
4. Combine like terms to get 80 = c²
5. Take the square root of both sides of the equation to get c = 8.94 .
