<p>Again, for number 32 the range is all numbers greater than -1.38, not -1.93</p>
<p>lol you guys got good @$$ memory…when i got back i could only remember like 7</p>
<p>haha i dont remember my answer but that was an easy question so hopefull i got it right</p>
<p>Well I wasn’t the one who posted #27, it was post #238 by Sixthsense and I merely copied his info. Note in #239 zmoose says its 16.91, I think we can rule they are equivalent.</p>
<p>so…27 and 49 nine are the same…</p>
<p>i think i remember 16.91…hahahaha</p>
<p>OK, they are the same problem. But my solution is correct there was no 15 or sin in the problem.</p>
<p>wait…I thought it required either sin or cosine to solve though…elaborate Jamesford please</p>
<p>u could use sine if u want lol</p>
<p>but it was quickest to use cosine</p>
<p>Triangle BAC has A = 43 degrees, AC = 12.43 (close enough), what is AB?
about 16.9</p>
<p>So it’s a cosine problem, cos 43 = 12.43/AB. AB = 12.43/cos 43 ~ 16.9
12.43 isn’t exact, but it was 12.something</p>
<p>wait, it’s just using the angle given and dividing the length given by the cosine(or sine) of the angle, right?</p>
<p>if it’s 12.something, then the answer cannot be 16.9 though…</p>
<p>^ Why not? cos 43 is about .73135, so 12.43/.73135 ~ 16.9
I already said the 12.43 is not exact.</p>
<p>oh…freaking google calculator gave me the wrong answer. my bad…</p>
<p>Specifics don’t matter; we know it was a triangle problem where you are given an angle a side and need to find an another side and that the answer was 16.91 which is enough for indentification purposes.</p>
<p>Those last 2 problems are really bugging me lol.</p>
<p>They are probably simple ones like the (x-5)^3 = 15 as well.</p>
<p>anyone get last two? :P</p>

<p>yeah I probably wouldn’t worry about the last 2 since because if no one on CC remembers they’re probably really easy and obvious. and remembering 48 out 50 is quite an accomplishment. thanks so much Xeaqs8</p>
<p>yup thanks!!!</p>
