Let 'm' be the third angle of the triangle.
The value of k would depend on value of m. k = 180-(x + m)
To determine the value of m, there should have been some relation between m and y. Also, there is no relation between m and the exterior angle of the triangle(180-m). So, K can possibly take all the values given in options without violating any rule of triangle.
Waiting for OA to know if there is something that I am missing out here.
Thanks for the question.

I don't understand one part of your explanation. You wrote
Also, there is no relation between m and the exterior angle of the triangle(180-m)
I'm a little lost because, perhaps mistakenly, I think there is a relationship between m and the exterior angle = x + k. The relation: y, m and the exterior angle (x + k) lie on a straight line.
(I keep thinking, inaccurately so far, that we can set up two equations, one having to do with the sum of angles on a straight line, and another having to do either with the sum of angles in a triangle, or the sum of two interior angles equaling an exterior angle).
So I'm curious to know what you mean by "no relation" in the quote above? Thanks!
