Use the properties of similar triangles.34. Express x in terms of the other variables in this picture: http://www.flickr.com/photos/46210274@N07/4918073428/ (I drew it myself, I know it's kind of small, but it is a replica of the drawings in the packet)
Oh, okay, well, what are the properties of similar triangles, or where can I find them here on Purplemath?Use the properties of similar triangles.
Oh, alright! I thought that would just be too simple to work. >< When I get to this one, I'll return with the finished product!Hint: For pairs of similar figures, the pairs of corresponding sides are proportional.
One way ....Okay, I've got another one from question 31. It's letter c, and as before, I'm supposed to write it as one equation, but this one involves sine and cosine:
x=sin t
y=cos t
I need some help here. What I did was:
t = arcsin x
y = cos (arcsin x)
But that can't be right, and if it is, I don't know how to complete it.
