Question

Find the value of X leave your answer in the simplest radical form :))

Answer 1

A

Explanation:

For this, you use the Pythagorean Theorem (
`a^2 + b^2 = c ^2`)

You have the value of a (13) and the value of c (15), so you can substitute that into the formula:

`13^2 + b^2 = 15^2`

`169 + b^2 = 225`

subtract 169 from both sides

`b^2 = 56`

`b = √(56)`

Putting it into simplest radical form,

b =
`2√(14)`
