For distributions that have outliers or are skewed, the median is often the preferred measure of central tendency because the median is more resistant to outliers than the mean.
Answer:

Step-by-step explanation:
1. Given WX>XY.
2. Then angle 3 has larger measure than angle 4, because angle opposite longer side is larger angle. This means that

3. Consider exterior angle 1. By the exterior angle theorem, the measure of the exterior angle is equal to the sum of the measures of remote interior angles. Then

4. Note that angle 2 has positive measure and then

5. Since
and
by the transitive property,

If K= 6, we simply substitute 6 where we see K, meaning plug in 6.
K=6
5+(6)=11
