Answer:
4.2
Step-by-step explanation:
As you should know, the Pythagorean Theorem says that the length of the sides of a right triangle are always related to each other in a way so that a leg squared (a^2) plus the other leg squared (b^2) is equal to the hypotenuse squared (c^2). Therefore, 3^2+3^2=c^2 9+9=√18
√18≈4.2
