Answer 1

Answer:

3$\sqrt{2}$

Step-by-step explanation:

Use the pythagorean method: a^2 + b^2 = x^2. Your a and b are both 3, and your c is x, so...

3^2 + 3^2 = x^2

9 + 9 = x^2

18 = x^2

$\sqrt{18}$ = x

(18 = 2 * 3 * 3, 3 has a pair, take that out)

3$\sqrt{2}$ = x

Answer 2

Answer:

$3\sqrt{2}$

Step-by-step explanation:

$x^{2} = 3^{2} +3^{2} \\x^{2} = 9+9\\x^{2} = 18\\x= \sqrt{18} \\x= \sqrt{9*2} \\x=3\sqrt{2}$
