Answer:
Step-by-step explanation:
You can use the Pythagoras Theorem to solve this problem:
For a given right triangle with right-angle side lengths of [tex]A[/tex] and [tex]B[/tex], the hypotenuse (side opposite of the right angle) length can be found by the following equation:
[tex]A^{2} + B^{2} = C^{2}[/tex]
From the given picture, [tex]A[/tex] and [tex]B[/tex] are both 4, so we can plug those into the equation to get [tex]C[/tex].
[tex]C^{2} = 4^{2} + 4^{2}[/tex]
[tex]C^{2} = 16 + 16[/tex]
[tex]C^{2} = 32[/tex]
[tex]C = \sqrt{32}[/tex]
[tex]C = 4\sqrt{2}[/tex]
