Answer:

[tex]\large\boxed{A.)\ 2\sqrt5}[/tex]

Step-by-step explanation:

The Pythagorean theorem:

[tex]leg^2+leg^2=hypotenuse^2[/tex]

We have

[tex]\leg=2\\leg=4\\hypotenuse=x[/tex]

Substitute:

[tex]x^2=2^2+4^2\\\\x^2=4+16\\\\x^2=20\to x=\sqrt{20}\\\\x=\sqrt{4\cdot5}\\\\x=\sqrt4\cdot\sqrt5\\\\x=2\sqrt5[/tex]
