Find the value of x.

dimaraw [331]

Answer:

$2\sqrt{77}$

Step-by-step explanation:

Use the Pythagorean theorem. $a^{2} +b^{2}=c^{2}$

a and b are the two side lengths

c is the hypotenuse (value across from the right angle)

Plug in the values that you are given.

$a^{2} +4^{2} =18^{2}$

Solve for x

$x^{2} =18^{2} -4^{2}$

$x^{2} =308$

x= $\sqrt{308}$

$x=2\sqrt{77}$
