Step one is to draw and label the figure described herein.

You can find that angle B = 40^{o}, angle DCB = 20^{o}, and angle BDC = 120^{o}.

Then, since BC = 2017, you can find sides BD and DC, using the Law of Cosines (or Law of Sines).

That should get you started, if you're willing to do the work.

I do not insult the student; I merely apply the word to that student's statement.

Too many students are just dumping easy questions on the website, rather than attempting any logical steps.

I think that we can assume that no word problems are inflicted on students without first exposing them to examples and encouragement, such as "Let x = ..."

I think that they should be called to task to take responsibility for their learning, and to accept challenges, and pay attention to their classes and READING THEIR BOOKS.

I agree with all of your thoughts and have the same thoughts too, however I feel as tutors on a public forum, we should be as congenial as possible, even if we feel otherwise. I have thought about taking a break from answering questions here, due to many of the issues you mentioned and a general lack of appreciation from question-askers.

Shamin: do you understand the process, now, and do you have the answer? To check them, you can plot all of these points on graph (quadrille) paper--they should be collinear (all 4 on one line) and successive distances from one to the next ought all to be equal. This visualization can be helpful for most problems in 'coordinate geometry.'
