<p>I hope you’re right!</p>
<p>For the triangle one I got (50-X^2)/50.</p>
<p>Are you guys saying SAS for the questions with a bunch of pictures of triangles
and which are congruent? Was that choice D? And then A C and E were way wrong and then B was like both SAS and ASA or something right?</p>
<p>mh…i guessed i think 13.7 for the double triangle one…but i completely guessed. Do you know what you put?</p>
<p>For the slope one I put they the two horizontal looking ones have the same slope…i didn’t know how to prove they were exactly horizontal though :(</p>
<p>I think it’s:</p>
<p>c^2 (x^2) = a^2 + b^2 - 2ab cos C</p>
<p>X^2 = 25 + 25 - 50 cos C</p>
<p>X^2 = 50 - 50 cos c</p>
<p>X^2 + 50 cos C = 50</p>
<p>50 cos C = 50 - X^2</p>
<p>cos C = (50 - X^2)/50</p>
<p>@mathisfun…good guess. it was 13.7</p>
<p>@mathisfun </p>
<p>uhm i think i put the one below that (c?) with 14. something cuz I plugged it in and 13.7 i must have messed up and it didn’t work so i put 14.something ll…</p>
<p>for the 58? proof one i put SAS (pretty sure it was B) but I didn’t fully analyze them all. :/</p>
<p>Was 13.7 C? Thats what I guessed too.</p>
<p>@SccrScrub01 hahahaha are you serious?! i used my pencil eraser to guestimate 13.7 how do you do it?</p>
<p>Woohooo, that’s my new favorite irrational number (considering the 13.7 was rounded)And any definite answer for the triangle slope one? :P</p>
<p>Was 13.7 answer choice C/H?</p>
<p>@StanfordCS</p>
<p>YEAH pretty sure cuz 14. something was right below it and it was either the 4th or 5th choice</p>
<p>what were the other choices to the question with 13.7?</p>
<p>13.7 was correct. I did it with law of sines/Pythagorean theorem because I couldn’t remember how we did problems like that in Pre-cal. </p>
<p>What about that absolute value question? I totally blanked on that one for some reason…</p>
<p>|2x-a| < 3, solution set 1<x<4, what’s a
^ Something like that.</p>
<p>I didn’t think the section as a whole was very hard at all. I might’ve made a careless mistake or two.</p>
<p>^ </p>
<p>a = 5</p>
<p>What did you put for the line segment question when it asked for the lengths?</p>
<p>@NameNotTaken: Yeah, a = 5</p>
<p>What did you guys get for the last one? It was something like if (x+2) is a factor of a 3rd degree polynomial</p>
<p>I got 13.7 without the law of sines or guessing. Can someone please describe the problem so I can remember how to do it?</p>
<p>DANGIT I put A = 2.5 </p>
<p>can anyone elplain that one? I didn’t ahve time to…</p>
<p>l2x - al < or = to 3</p>
<p>1< or = to x < or = to 4
a is???</p>
<p>What answer choice was 5?</p>
