Quick Question
How would you guys go about doing this question?
My initial thoughts are: The bottom right corner, BCD would make 180 - 50 = 130 degrees. However, from there I don't know where to go as it's two individual triangles and the information given in both triangles is insufficient in helping us to find out anything else about the triangles.

Start by looking at the big triangle ABC and find angle ABC using the sine rule.
Try this and then try to continue. Post all your working if you get stuck.

Be patient
Your thread was at the top of the forum so it's not like people won't see it.You posting will make people think your thread has an answer - threads with no replies are the ones that people will look at most. Also, labeling the thread as 'postgraduate' doesn't help.

& What do you mean the big triangle? Don't you mean BCD?

No I mean the even bigger triangle ABC.

How can that be considered a triangle o.0

It has 3 sides : AB, BC and AC.

You may be postgraduate but this is GCSE level maths and should be marked as that.

I didn't think triangles could be looked at like that, as it was joined to another smaller triangle. Well, thanks I'll make sure to remember this.
One more question plz:

But surely if you use the sine rule you need either two angles and one side or two sides and one angle?

Correct.
But we do have enough : we have AB, AC and angle ACB which is 180 - 50 = 130.

I'm traveling now so won't be able to help for a few hours.
You could try posting a new thread with this question and don't reply to it. That will encourage people to reply to an unanswered thread.
