Sagot :
Answer:
3[tex]\sqrt{2}[/tex]
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
[tex]\sqrt{18}[/tex] = x
(18 = 2 * 3 * 3, 3 has a pair, take that out)
3[tex]\sqrt{2}[/tex] = x
Answer:
[tex]3\sqrt{2}[/tex]
Step-by-step explanation:
[tex]x^{2} = 3^{2} +3^{2} \\x^{2} = 9+9\\x^{2} = 18\\x= \sqrt{18} \\x= \sqrt{9*2} \\x=3\sqrt{2}[/tex]
