1.	Draw a 30-60-90 triangle. Label all angle measures and side relationships. Using the side relationships from the figure, show that the following trigonometric identities hold true for the given angles:

anonymous · Answer

A) tan 60 degrees = $$\frac{ \sin 60 degrees }{ \cos 60 degrees}$$

anonymous · Answer

B) $$\sin ^{2}$$ (30 degrees) + $$\cos ^{2}$$ = 1

First we need to draw the triangle.
Did you have an idea for that part?

?

accessdenied · Answer

It's a triangle for sure, but let's use the specifications:
  a 30-60-90 triangle.  That means we have a 30 degree angle, a 60 degree angle, and a right angle.

Wait. No.

anonymous · Answer

Or yes. Idk. I think thats right

accessdenied · Answer

Much closer.  It will work for us now.
Let's label the angles first.

Okay

accessdenied · Answer

So, do you remember the side ratios of a 30-60-90 triangle?
Or any information regarding the sides is good to recite here.

Sorry, the site seems to be acting up but I don't have the time to be waiting for it! Here is a resource on 30-60-90 triangles. http://www.mathopenref.com/triangle306090.html If you need more help, try to tag others or bump the question! Sorry to leave suddenly!
