Answer:

x = 8.5

Step-by-step explanation:

Do solve this equation you will need to use the pythagorean theorem.

First start by plugging in the numbers.

[tex]7^{2}+ x^{2}=11^{2}[/tex]

The x will be what you are solving.

7 squared is 49 and 11 squared is 121.

[tex]49+ x^{2}=121[/tex]

Move the variable to one side.  Do this by subtracting 49 from both sides.

[tex]x^{2} = 72\\[/tex]

Now find the square root of 72 in order to get rid of the x squared.  (Convert to decimal if needed).

x = 8.5

Hope this helped.
