Does anyone know the answer to the question? i will mark brainliest

Hello!

Because this is a right triangle, we can solve for "X" using the Pythagorean Theorem. The Pythagorean Theorem can be stated as follows:

c² = a² + b²

In this case, C is the hypotenuse (X) while A and B represent the other two sides. We'll begin by inserting any known values into the formula above:

c² = (4)² + (9)²

Simplify the right side of the equation and combine like terms:

c² = 16 + 81
c² = 97

Now take the square root of both sides:

c = 

We have now proven that C (hypotenuse "X") is equal to .

I hope this helps!
