<p>Post all math section questions here.</p>
<p>are we allowed to discuss answers yet?</p>
<p>yes, only the college board doesn’t allow this.</p>
<p>Soooooo easy</p>
<p>was the sin s/t and cos tv like the answer g?</p>
<p>does anyone remember the angle one near the end…they gave you 132 degrees…the answers were 84, 86, 88, 89, and 92 i think…</p>
<p>I think the angle’s 88. I did the math and that’s what I got, but I could have made a mistake along the way.</p>
<p>I remember putting 88.
Something along the lines of three angles being congruent (So 1 side of triangle = 44)
Then the other was was like Alternate interior angle + property of line = 48
180 - 44 - 48 = 88</p>
<p>yeah the angle was 88</p>
<p>i said 84 and I’m pretty sure I was right.</p>
<p>its 88. does anyone remember the trig problems where it asked you what was csc theta from sin=0.4?</p>
<p>5/2
csc theta = 1/sintheta
1/0.4 = 5/2</p>
<p>the csc was 1/0.4 which is 5/2</p>
<p>the angle was definitely 88.</p>
<p>and the sqrt(s/t) + sqrt (t/s) was the last choice, which i think was s+t/sqrt(rs) i think</p>
<p>coordinates for the counterclockwise vector were (-3,2)</p>
<p>all sounds good to me…
How about the A B C D one, which one doesn’t always equal the other…i can’t remember what the specific answer was but i think the multiple choice response was B?</p>
<p>I agree with 88, 5/2, and s+t/sqrt(rs)… I thought that coordinate one was (-2,3)… I could very well be remembering incorrectly though. But I just kept the y value and made the x value negative.</p>
<p>88? really? ■■■
A=B
c=square root of B
A cannot equal C</p>
<p>underdog, i think you forgot about the 90 degree part, which means the new slope would be the opposite reciprocal. so you switch the x and y and make the x negative. the actual answer is (-3, 2)</p>
<p>Anyone get 24 for the perimeter of the rhombus? i just multiplied the two diagonals and divided by two</p>
