Blue Book Math question

<p>As you progress in the Blue Book's practice tests, there seems to be less threads on explaining the more challenging math questions. Can anyone help me with the one from test #6 section 2 problem 18?</p>

<p>In the figure above, AB = BC and DE = EF= DF. If the measure of angle ABC is 30 degrees and the measure of angle BDE is 50 degrees, what is the measure of angle DFA?</p>

<p>EDIT: I have more questions but wanted to see if anyone could help before I proceeded to add more.</p>

<p>Also, the video solutions at SATquantum.com are pretty nice.</p>
