Thanks MathsGod but you need to get rid of that word 'doubled' (you used it twice I think)

Doubled means multiply by two and that in NOT what you are doing here.

The word you need is 'squared' or simply 'multiplied by itself'     

The rest is good :)

Much better Dbg  

I've given you the points now.

It would have been a tad better if you had explained where your 5 came from :)

I know I explained it in a later post but it could have been with yours as well :)

Hint:

These 2 angles are supplementary.

complex numbers can be graphed on a number plane the horizontal axis is the real part and the vertical axis is for the imaginary part

if the Imaginary part is neg the point will be below the real (x) axis.

I'd post a graph but I am on my phone so I can't. :(

No Dbg, you have found the mean(average) not the median.

The median is the MIDDLE score, or the average of the 2 middle scores if there in not just a single one.

Before you 'pull out' the middle score, you have to put them in order from smallest to largest.

That was already done for this set of scores :)

$$\underset{\,\,\,\,^{\textcolor[rgb]{0.66,0.66,0.66}{360^\circ}}}{{cos}}^{\!\!\mathtt{-1}}{\left({\mathtt{0.833\: \!333\: \!33}}\right)} = {\mathtt{33.557\: \!310\: \!107\: \!427^{\circ}}}$$

I just typed acos(0.833333333) into the calc

Einstein, do you think that the student who asked this question will understand your answer?

Just edit you answer Dbg :)

Thanks Dbg :)

Does it translate well or badly Dbg?
