<p>@gorilla 7/cos56 is correct. Also, i think it is possible that -2 could earn you a 36. This was definitely a tough math section.</p>

<p>Did anyone get the answer 15 for anything</p>

<p>I don’t think the curve will be that great. I studied more, but this was easier than June.</p>

<p>What was the length of the arc</p>

<p>7/ cos 56</p>

<p>That one???</p>

<p>No it was the distance the guy walked</p>

<p>I had that^ but changed it :////. Hoping for a 31-33</p>

<p>I can’t believe I flippin’ got a 34 on June’s, but got wrecked on this one. Also, I’m so angry I didn’t guess D towards the end. I would’ve gotten 3 more correct. >.<</p>

<p>It was the distance between 2 points from a 90 degree right angle</p>

<p>So just the P. Theorem?</p>

<p>Noo it was arc formula because it had the radius from the angle & an arc & the degree was 90 since it was from a right angle and you needed the distance traveled</p>

<p>what numbers were we given for the arc one?</p>

<p>howd you guys get rid of the pi on the arc one? 1/4 C left me with pi but none of the answer chocies had pi.</p>

<p>I think r was 10 on a 90 degree angle i got like 15.7 but the answers were 15 & 17 so idk what it wanted</p>

<p>Was the answer to one of the questions 50 degrees? it was the one with the triangle and the lines sticking out.</p>

<p>It was 1/4 of a circle points A and B i think the bottom part was 10 it wanted the arc distance >.< answers were like 11 13 14 15 17 i forget i know 15 & 17 was there</p>

<p>Yeah I needed help on the arc one too, was it straight line distance?</p>

<p>I dont remember this question. Can anyone explain it?</p>

<p>what was the exact question for the distance the guy walked? i dont remember that… was it toward the beginning or middle</p>

<p>Nah just 1/4 of a circle cut out the points were on the arc so i couldnt use p. Theorem</p>

<p>Basically it was from (10,0) to (0,10) the r was 10 angle was 90 but it wasnt a straight line it was on an arc and it wanted to know how far it was</p>
