Alright, really just basic vocab testing happening here.
What does supplementary mean? It's not like a vitamin.
It just means that when two angles supplement one another they create an
angle of 180 degrees.
Like this...otherwise known as a line. So what angle
is located next to angle 10 that creates a straight line?
Well both angles 9 and 14, but 9 isn't an option so our answer is
angle 14. There we go. So boom! The answer is B.
