Understandable solution until the "reflex angle" statement.
Reflex angle is the larger angle. It's more than 180 degrees but less then 360 degrees.
After finding angle ABC, which is the smaller angle, you have to take 360 - the answer in order to get the reflex angle (the bigger one) at the same point.
