Let ABC be an isosceles triangle with AB=AC.Suppose that the bisector of angleC meets AB at D and that angleA is 100.if BC=2017, FIND AD+CD

I could find AB and AC with the help of trigonometry. But still I am struggling.. I have been trying to do this for about a month.. All I need is a guideline

Not cool to insult the students!!!! Remember that potential clients watch what u write and may not like what they see.

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.'
