<p>@omgitsvicki i put 50 hbu???</p>
<p>I am pretty sure I put 14 for that arc one with thr legs of the triangle being 10 and the angle between them 90.</p>
<p>Anyone else got 14 and was there also 15 as a choice??</p>
<p>@headed2great, I got 50 at first, but I double checked and ended up with 60. So, I put 60 …</p>
<p>What was there to double check? The interior angles added up to 130 meaning the third angle was 50. Since they met at an X that means the degrees in front of each other have to equal each other.</p>
<p>I forgot the proper name of my explanation.</p>
<p>Vertical angles</p>
<p>Please correct me if I am wrong.</p>
<p>Guys were there questions that we had to use sin cos tan function directly? For example: What is Sin 40. Cuz my calculator was in radians for whole time. Please respond :(</p>
<p>Nope . Not that I remember.</p>
<p>What was the problem about mean?</p>
<p>Okay, for the circle walking flagpole question, it was 15. They specifically asked for the distance he walked, which was one quarter of the circumfrence of a circle with radius 10. If they wanted to know the other side of the triangle, there would have been no point in including the whole part about him maintaining that distance of 10 while he walked. Thus, you get 15.7 and it asked for the closest answer, which was 15 because 16 was not an answer and the next one was 17. 15 100% sure.</p>
<p>Thank you jman! I figured thats what they wanted</p>
<p>Also, that question was too far into the test to be a simple p theorem question. The equation for circumference is a little more involved and appropriate for the last 20-15 questions of the test.</p>
<p>any time, cole.</p>
<p>I think i guessed 15</p>
<p>well, you guessed well, my friend.</p>
<p>What did the initial problem give us again jman?</p>
<p>it said that bob (or whoever it was) started at one point ninety degrees from a flagpole and walked in such a way that he revolved around the flagpole while remaining the same distance away. We saw that he walked 1/4 of a circle with radius of 10. Thus we can calculate that the whole circumference was 20pie, which is roughly 60-62. Then, we divide that by 4 and get 15.7. The question asked which of the following numbers was closest to the distance he walked, the closest choices were 15 and 17. 15 is closer, so 15 is the answer.</p>
<p>No, didn’t it say how far away from the flagpole he was at the beginning? If that is right, then then the answer should be 10sqrt(2), or 14. Also, if 15.7 was the right answer, then 16, the closest whole number, would be an answer choice.</p>
