Question

PLEASE HELP ME (answer only if you know) please do step by step

Answer 1

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.

$7^{2}+ x^{2}=11^{2}$

The x will be what you are solving.

7 squared is 49 and 11 squared is 121.

$49+ x^{2}=121$

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

$x^{2} = 72$

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.
