Step 1:
I'll solve this step-by-step using the Pythagorean Theorem.

Step 2:
: Identify the right triangle

- We need to find the length of the third side ($$x$$)
- We have a right triangle with two known sides - One side is 6 units long - The other known side is 8 units long

Step 3:
: Recall the Pythagorean Theorem

Where $$c$$ is the length of the hypotenuse (longest side)
The Pythagorean Theorem states that in a right triangle:

Step 4:
: Substitute known values

- Let $$c = x
- Let b = 8

Step 5:
: Apply the Pythagorean Theorem

6^{2} + 8^{2} = x^{2}

Step 6:
: Calculate

36 + 64 = x^{2}
100 = x^{2}

Step 7:
: Solve for x

x = \sqrt{100}
x = 10

Final Answer

x = 10
