Question

12) In the given figure, p and q are two parallel lines.
AB and BC are line segments such that angle BAD =
140° and angle BCE = 120°. Find the measures of the
reflex angle ABC and the smaller angle ABC at B. You
may have to do a small construction to proceed
with your proof. Think what you have to do.
