Hi icystrike! :smile:

Your diagram looks fine …

you've correctly drawn the three roots at -20º, 100º, and 240º. and the line you've drawn is the correct line.

What is worrying you about that? :confused:
 
cos I'm self-learning and does not have any tutor , thus , I'm here to check with you if I'm on the right track . Thanks tiny-tim ! (=
