<p>Problem:find the slope of a 30 degree line</p>
<p>Solution:tan 30</p>
<p>bump
any others</p>
<p>pretty clever, didint think of that</p>
<p>I just did a quick unit circle, basically the same thing. I was in no rush for time , so I didn’t worry much about how I was solving it.</p>
<p>easy solution for the x^-y problem?</p>
<p>The only solution for a question asking the slope of a 30 degree line is tan 30.</p>

<p>Not true at all. Draw a line 30 degrees above the x axis on the coordinate plane. Drop a perpendicular, and you now have a 30-60-90 right triangle. Slope = change in y/change in x. Opposite the 30 degree angle is the change in y. Opposite the 60 degree angle is the change in x. The ratios of these respective sides, due to 30-60-90 triangle properties, is: x to x√3, respectively. Slope = x/x√3 = 1/√3 = √3/3</p>
<p>You’re not expected to know trig for the SAT, but of course it can help.</p>
