Question

find the value of x. Give the answer in simplest form.
1st side of the right triangle: x-2. 2nd side: 8. 3rd side: x

Answer 1

While not essential here, a diagram showing this right triangle with all the side lengths marked would be nice. But the problem can be solved without a diagram.

The key word here is "right" as in "right triangle."

What important theorem applies here?

Answer 2

pythagorean theorem
