<p>That’s exactly what you’re supposed to do^ you probably made a calculator error</p>
<p>@N1trer1cal the best way is to use law of cosines to get the third side, then heron’s formula to find the area of the plot. You have to convert what you got from feet to acres.</p>
<p>That’s what I did, and I got an answer of 3.95~. </p>
<p>And I don’t think that Heron’s was the best way. The .5xsinCxAxB is certainly the most convenient and time efficient.</p>
<p>Was 9 even an answer choice? I checked my calculator history and I typed everything in and got 3.95 as the answer, so either I did put 4 or somehow I missed the 3 in the front (I will be so mad lol…)</p>
<p>This thread is making me feel worse and worse about my score. I feel like I got around a 700.</p>
<p>Oh well, I felt good about the U.S. History test though, so at least I have that going for me…</p>
<p>what did y’all get for that question with the diagram of a right triangle within a right triangle? it asked about what tanx is equal to. was it tany?</p>
<p>IT WAS TANY</p>
<p>Aw man for the that sine problem I put positive 2 point something, heard it was negative…</p>
<p>Darn it, I put cos Z…</p>
<p>thanks @StanfordWOW 
also, what was the cos a = 2/5 question? i totally don’t remember that for some reason </p>
<p>The greatest circle one is most definitely 0. A great circle is defined as a circle that has the diameter of the original sphere, while also passing through the center point of the sphere itself. A circle between points A and B may be a great circle, but does not pass through the center point of sphere. Answer is therefore 0.</p>
<p>@TheTrueOne If you look a few pages back there are a lot of explanations as to why it’s 1. </p>
<p>3 omitted 5 wrong. I think that’s pretty much it. Well, I’d be OK with that. Given how tough it was, I could get 750+!</p>
<p>Yo anyone remember the question (#14 I believe) that asked for the ratio between x and y? Was it 12 to 5?</p>
<p>@vivalamelanie I heard it’s negative 2.27 or something like that…I picked positive 2.27.</p>
<p>@Ntrer1cal i got 12/5 too</p>
<p>Typed the entire 2x4x6x8x12x14… question into Wolfram Alpha and the last digit is a 6, unless I misinterpreted the question</p>

<p>Agh. Missing 8 might even be an 800.</p>
<p>i think that I got that units digit one correct despite not knowing what that meant… just because 6 was the first digit in the exponent in scientific notation.</p>
