Find the length of the third side. If necessary, write in simplest radical form.

Answer: [tex]3\sqrt{3[/tex]
Step-by-step explanation: use pythagorean theorem to solve this. which is a^2 + b^2 = c^2
lets say b=3 and c=6. plug this into the equation. (6)^2 - (3)^2 + = 36 - 9 which is 27 = c^2. to get c from c^2, square root the c^2 value
the square root of 27 is [tex]3\sqrt{3[/tex] in simplest radical form
