The length of AC (x) is approximately 9.49.
To find the length of AC, we can use the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides.
In this case, AB and BC are the two sides, and AC is the hypotenuse.
We have AB = 8 and BC = 5, so we can use the equation
to find AC.
Substituting the values, we get
= 64 + 25 = 89.
Taking the square root of both sides, we find AC ≈ 9.49.
Therefore, The length of AC (x) is approximately 9.49
