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.
