Step-by-step explanation:

By using cosine rules:

6/sin45° = b/sin90°

b = 6× sin45°/sin90°

b = 9.124(3d.p)

Also,

using Pythagoras theorm of right-triangle

b² = 6² + a²

9.124² = 6² + a²

83.247376 = 36 + a²

83.247376-36 = a²

47.247376 = a²

√47.247376 = a

6.874 = a

If I understand what you are asking, you can use the median as an average since it is not affected by the mean ( median is a measure of center).  Since a mean is affected by outliers, it might lower the score if there are very low outliers. But note that if there are outliers way <em>greater </em>it can increase the average. You can use the Inter Quartile Range if shown on a box plot ( measure of variability).
