Answer:
6.36
Step-by-step explanation:
we can solve this using pythagorean theory
[tex]a^{2} +b^{2} =c^{2}[/tex]
we can subsitute a or b for w
and we also know that w is equal to the other leg and 9 is the hypotenuse
edit the function: [tex]2w^{2}=9^{2}[/tex]
[tex]2w^{2}=81[/tex]
divide both sides by 2: [tex]w^{2}=40.5[/tex]
take the square root of both sides: [tex]\sqrt{w^{2} }=\sqrt{40.5}[/tex]
simplify: w=6.36
