Answer:

85°

Explanation:

Line segment AB || line m

Therefore, BC is transversal.


\therefore m\angle ABC + (m\angle ACB +m\angle A D) = 180\degree


\therefore m\angle ABC + (55\degree + 40\degree) = 180\degree


\therefore m\angle ABC + 95\degree = 180\degree


\therefore m\angle ABC = 180\degree -95\degree


\therefore m\angle ABC = 85\degree
