The leaning tower of pisa leans toward the south at an angle of 5.5 degrees. One day a shadow was 90 m long and the elevation from the tip of the shadow to the top of the tower was 32 degrees
1)Determine the slant height of the tower.
First I found all the angles and then...
If sin theta = \frac {-4} {7} and \frac {3 pi} {2} < theta < 2 pi then determine the exact value of \frac {1} {cot (theta)}
I don't know where to start I know to set up a circle with a cartesian plane but what am I supposed to do? :rolleyes:
I don't have the answers in the back of my book and I really want to know if i did this correctly since its graded. the Problem is: Let the region bounded by x^2+y^2=9 be the base of a solid. Find the Volume if cross sections taken perpendicular to the base are isosceles right triangles.
i...
I was wondering if you can find the sides of a right triangle if you only know the angles of the triangle...i couldn't think of a trig ID or any law..if there is, id like to know it, thanks.
ok, I'm in first year coolege and we're doing some review from high school work.. but i can't for the life of me remember how to do one of these questions and i can't seem to get past this one part or at least figure out how to prove that it is what i think it is.
it's going to be a bit...
Sorry to bother you guys.. but if there is someone out there that is good at math and wouldn't mind helping me.. could you aim me sn:"euphoriet" thanks.
Please move this post if necessary as I was not sure which forum it would be best suited to.

I'm still not quite sure about the flying triangle reports. I am convinced that these are real craft that are often seen as reported, but some good reports such as those from the Illinois police - who...
I found a neat problem on the web you can look at it http://physics.harvard.edu/undergrad/prob14.pdf I've always had fun with these find the angle problems but my solutions on this one seemed a little bit weird. Anyone want to let me know what they got? Heres what I found angle BCA = 20 and...
