Answer: [tex]a=\frac{9}{2}, b=\frac{15}{2}[/tex]

Step-by-step explanation:

By the geometric mean theorem,

[tex]\sqrt{8a}=6\\\\8a=36\\\\a=\frac{36}{8}=\frac{9}{2}[/tex]

Using the Pythagorean theorem to solve for b,

[tex]6^{2}+\left(\frac{9}{2} \right)^{2}=b^{2}\\\\36+\frac{81}{4}=b^{2}\\\\\frac{225}{4}=b^2\\\\b=\frac{15}{2}[/tex]
