Question

Anyone please???????

Answer 1

B sqrt17

Explanation:

a^2+b^2=c^2

Answer 2

`\boxed{\sf B)\: x=√(17)}`

Explanation:

Use the Pythagorean Theorem

The equation for the Pythagorean Theorem is
`\tt a^2+b^2=c^2`

* a and b are the lengths of the legs, and c is the hypotenuse.*

(To know which side is the hypotenuse look at longest side which is across the right angle).

a= x, b=8, c=9

`\sf a^2+b^2=c^2`

Let's Plug in the side lengths:

`\sf x^2+8^2=9^2`

Evaluate 8^2 and 9^2:

`\sf x^2+64=81`

Subtract 64 from both sides:

`\sf x^2+64-64=81-64`

`\sf x^2=17`

Take the square root of both sides:

`\sf x=√(17)`
