Answer:
[tex]x=3\sqrt[]{5}\approx6.7[/tex]
Step by step explanation:
To find the value of x, we can use the Pythagorean theorem, which is represented by the following diagram and formula:
Then, if a=6 and c=9, let's find b(x):
[tex]\begin{gathered} 6^2+x^2=9^2 \\ x=\sqrt[]{9^2-6^2} \\ x=\sqrt[]{81-36} \\ x=\sqrt[]{45} \\ x=3\sqrt[]{5}\approx6.7 \end{gathered}[/tex]
