You need to use the Pythagorean Theorem. This is:

Where "a" is the hypotenuse and "b" and "c" are the legs of the right triangle.

In this case you can identify that:

Therefore, you can substitute values into :

Finally, you must solve for "x" in order to find its value.

You get that this is:

it’s supposed to be -4+45=41
