Step-by-step explanation:

The Pythagorean Theorem says if you have a right triangle, then relationship between the three sides is the sum of the square of each leg is the hypotenuse squared.

So

where a and b are legs and c is the hypotenuse.

Plug in your a,b, and c. In this case it is a,6, and 8.

This means we have

Simplify where you can before we begin the solving (the moving around of things to other sides).

Now time for the solving. We are first going to get by itself.

To do this, we just need to subtract 36 on both sides giving us:

Now to get rid of the square on a, just square root both sides:

.
