<p>@bamtam I’m almost positive it was 6 + 2root3</p>
<p>@lalala321 9.01 was not an answer. That was for find the possible length of a side of triangle given two are 5 and 4</p>

<p>The buy 3 get 1 free question what was the answer…this was the hardest question on the test and it was only like question 9…</p>
<p>The law of sines?</p>
<p>Triangle with angle 45 was paired with 4rt3
Triangle with angle 60 was paired with nothing.</p>
<p>Sin45/4rt3=Sin60/x
x=Sin60*4rt3/Sin45
If you use a unit circle you don’t need a calculator to calculate sines.</p>
<p>x = (rt3/2*4rt3)/(rt2/2)
x = (4rt3rt3/2)/(rt2/2)
x = (12/2)/(rt2/2)</p>
<p>You can just cancel out the common denominators here.</p>
<p>x = (12)/rt2</p>
<p>multiply the top and bottom by rt2</p>
<p>x = 12rt2/rt2rt2
x = 12rt2/2
x = 6rt2</p>
<p>The answer was 6 root 2.</p>
<p>It was 6+2 sqroot 3 (or 6+ 3 sqroot 2 I don’t remember the exact answer was). I checked on my calculator. Yay for programs lol.</p>
<p>Okay, to explain the triangle problem…
The sides were 4, 5, and x. You were given choices to what the value of x could be. The triangle inequality theorem states that no side can be longer than the sum of the other two sides and no side can be shorter than the difference of the other two sides. Therefore, x cannot be greater than 5+4=9 or less than 5-4=1. 9.01 is greater than 9. The answer was 1.9.</p>
<p>@sat</p>
<p>25% less</p>
<p>thats what i got too</p>
<p>thank you drac313 it was either that or 33.33% and i ran out of time trying to rationalize the answer and picked 25!</p>
<p>@Jimmypod
You are finding the wrong side length. You were supposed to find the length of the side opposite to the 75 degree angle.</p>
<p>wasn’t the cake one 8/15? 1/3 + 1/5</p>
<p>The grid-in one with the pie charts and asked about the degrees</p>
<p>126?</p>
<p>The one with cats and dogs in a pet shop</p>
<p>28?</p>
<p>The one that asked for the smallest angle.</p>
<p>I believe it was z, which was 50 degrees.</p>
<p>lol how was that the “hardest”</p>
<p>@stressedouttt
You forgot to account for the fact that they were halves.</p>
<p>it was 1/10 + 1/6 because you needed to make it out of the whole cake not just the halves</p>
<p>Ugh, can’t believe I missed that xyz question! Do u guys think that was the experimental section??</p>
<p>@ stress</p>
<p>no it was 1/6 + 1/10</p>
<p>@yankees</p>
<p>it as for the difference between the two which I believe was 126</p>
<p>@yankeesfanatic</p>
<p>Those all look right. I would congratulate you but I’m a red sox fan :p</p>
<p>1/3 of one half plus 1/5 of one half
1/6 + 1/10
5/30 + 3/10 = 8/30 or 4/15</p>
<p>@zzzzzz oh gotcha. that’s annoying though -_-</p>
<p>@yakees I got the same answers</p>
<p>For the PQRS in a line one, was the answer 1/4? I don’t really remember what I put.</p>
<p>@meatkabob
Yes I got 1/4 too.</p>
