Please help me , ASAP! Thanks!

<p>Hey Penn students/prospies etc.!</p>

<p>Well, so I'm a junior in high school and right now I have a B+ (92.34 ...arghhhh!!) in my AP Calc class.</p>

<p>Since I'm so close to getting an A (less than .2 away), my teacher gave me this problem to do for extra credit and said that I could get any help I wanted (thank god, or I would never be able to do this).</p>

<p>So I've uploaded the problem online and you can see the problem here: <a href=""&gt;;/a&gt;&lt;/p>

<p>The text for the problem is on the bottom and the diagram is the one on the right (exercise 28).</p>

<p>So I would really really really really really greatly appreciate it if one of you guys could figure this out and tell me how to do it (eg. where to draw auxilary lines, steps in proof).</p>

<p>Lol, i dont even get why I get a geometry problem for AP Calc but w/e.</p>

<p>So any help greatly appreciated! If you have any questions PM me! Please try to get this by tonight! </p>

<p>Thanks so much.
