Step-by-step explanation:
In any right triangle, the Pythagorean theorem states:
, where
and
are two legs of the triangle and
is the hypotenuse.
Plugging in given values, we have:
![12^2+VU^2=18^2,\\144+VU^2=324,\\VU^2=180,VU=\sqrt{180}=\sqrt{36}\cdot \sqrt{5}=\boxed{6\sqrt{5}}](https://tex.z-dn.net/?f=12%5E2%2BVU%5E2%3D18%5E2%2C%5C%5C144%2BVU%5E2%3D324%2C%5C%5CVU%5E2%3D180%2CVU%3D%5Csqrt%7B180%7D%3D%5Csqrt%7B36%7D%5Ccdot%20%5Csqrt%7B5%7D%3D%5Cboxed%7B6%5Csqrt%7B5%7D%7D)
All of the numbers are the mode, so it is
1982, 1988, 1989, 1994, 1995, 2005
