SAT March 2012: Math Thread

<p>Let's start just a math discussion here. Post answer/reasoning. Thanks!</p>

<p>I feel so lame. On the question with the 4root3 triangle and xy angles, I ended up using the law of sines. ): I got the right answer, but I feel like I went outside the scope of the test…</p>

<p>What was the answer again?</p>

<p>I had to use law of sines too. How strange.</p>

<p>I also used the law of sines, but I didn’t remember if it only applied to right triangles so I spent extra long on that problem. But alas I did confirm E in both methods</p>

<p>What was the right answer? I didn’t have time to check it.</p>

<p>it was E. i used the law of sines too :confused: then when I got home i realized, just draw a line down from the 75 degree angle and now you have two triangles, one 30-60-90 where you know the hypotenuse and can find the other legs, and the other was a 45-45-90 where you know one of the legs because it’s in the previous triangle.</p>

<p>do any of you think 3 omitted and one or two wrong (one being grid in the other mc) is above a 700?</p>

<p>what do you guys think will -1 on math be?</p>

<p>@flying eagle - that would bring you to either a 50 or 49 raw score depending on how many you got wrong. That could definitely be above 700. I would say between 690 and 720</p>
