Explanation:
In order to solve x, we have to use Pythagoras' theorem.
Pythagoras theorem: a²+b²=c²
So the longest side of a right angled triangle is always called the hypotenuse, which is also known as 'c'.
The shorter ones can either be 'a' or 'b'.
Let's make the side of 6 known as 'a'.
So now we have our 'c' and 'a', and we want to find out b (or in this case it's x).
So the formula now would be
c²-a²=b²
Now let's make the equation
10² - 6²=b²
100 - 36 = b²
64 = b²
Square root both sides it'll be:
8 = b
Since b is also your x,
Answer:
x = 8
