Steps to solve, don't give solution. Cause this an assessment problem

What does the statement

BD bisects <ABC​

mean to you?

Please show us what you have tried and exactly where you are stuck.

Angle B was bisected. So what can you say about x-2y and y?

I think this is an invalid problem.

It looks, in the diagram, as if angle ABC is a right angle, and also as if triangle BDC is isosceles; but neither of these can be assumed without being told (in words, or by a marking). So the diagram tells us nothing new that we could use to find x and y. So there is no valid answer for (b), and no unique answer for (c).

In particular, I get different answers if I assume either of the two possibilities I mentioned! So no solution completely fits the appearance of the diagram.

So I would answer (a), and then state that there is no second equation to write. Or, I would ask my teacher if I am expected to assume something from the picture.

Well, I am glad you posted this because I was racking my brain for 60 year old memories of theorems of plane geometry.

Of course, this may be one of those rare instances where we were not given the complete problem.
