What is the value of x? please hurry.

Artist 52 [7]

Answer:

Step-by-step explanation:

Use the pythagorean theorem. The hypotenuse (c) is 10, and one of the sides, let's say (b), is 6. Therefore, we need to solve for a and plug and chug. Let's do that:

$c^2 = a^2+b^2$

$a = \sqrt{c^2-b^2}$

Now let's plug in what we know:

$a = \sqrt{10^2-6^2} = \sqrt{64} = 8$

Therefore, a = x = 8
