Question

Please help me with this!!

Answer 1

8.06

Explanation:

Use the Pythagorean theorem:

`a^(2) +b^(2) =c^(2)`

The hypotenuse is always the slanted side, or c (x in this picture), but the other numbers can be interchanged. Doesn't matter.

Plug the numbers 4 and 7 into the formula.

`4^(2) +7^(2) =c^(2) \\`

Now evaluate them to get
`c^2`

16+49=65

To get c, take the square root of 65

`√(65) = 8.06`
