Step-by-step explanation:

You can find the missing leg using the Pythagorean Theorem. The two legs of the triangle, squared, add up to equal the hypotenuse of the triangle, squared. The hypotenuse is the side directly across from the right angle and is always the longest.

To find the missing side:

10^2 - 8^2 = 36.

Then you find the square root of 36, which is 6, the missing side length.

This satisfies the Pythagorean Theorem:

6^2 + 8^2 = 10^2

36 + 64 = 100
