<p>Sorry I'm not posting this in the math thread, but it was talked about and I didn't get the explanation.</p>

<p>What's AF?</p>
<p>All of the triangles shown are similar triangles, meaning their angles are the same & their sides are proportional to the others.</p>
<p>So, in order to do this problem, you must find some additional sides & I think I ended up solving for 3 or 4 sides before finding AF.</p>
<p>Also, I think you're leaving out a given measurement... Is there one you've forgotten?</p>
<p>Here's what I remember finding, but I don't have the time to work otu the entire problem step by step at the moment for you--but you can Private Message me if you'd like. :(
CY=10
CD=8
DF=4
AC=24</p>
<p>AF=36</p>
<p>Sweeeet, I got 36 as well.</p>
<p>was this free response or no? and does anyone remember the other choices?</p>
<p>It wasn't a free response.</p>
<p>I believe the choices were:
24
28 (? could be mistaken on that)
32
36
40</p>
<p>JESUS, how can you remember the answer choices? Amazing lol</p>
<p>xD I have a mind for numbers, but I can't remember most of the CR QUESTIONS to save my life. Oh, & I remembered that after getting AC & CD I could eliminate A,B,C since A=AC & B=AC+CD. That'd why, haha.</p>
<p>Yeah I think I didn't read a given...</p>
<p>ARGH!</p>
<p>What else was given???</p>
<p>Anyone know?</p>
<p>I think either AC or AD was given. Can't remember which.</p>
<p>36 for sure.</p>
<p>Anyone have the one where adults and children were going on a ride? I got 16</p>
<p>Yeah! I got that :)</p>
<p>Okay I'm going to slit my wrists now.</p>
