While we seem to be OT...
lets help NovceGuru with his girlfriends trig! Its been about 4 years since I've done this stuff, its fairly simple, I just dont remember the process.
I'm pretty sure for the first one its tan 36 = a/48
and for the second one I think its cos 36 = c/48
After that i'm not sure what you do to find the variables...
Pretty basic stuff....just been a while
Thanks

OK brain, you don't like me and I don't like you. Let's just get through this and I can get back to killing you with beer.
It's a deal!

i don't think there's a way to do this problem without the cosine rule, and the cosine rule needs two sides and an angle, because the trig functions are ratios. for example
a/sin = b/sin = c/sin
if you have any 3 parts of this, you can solve for the rest.
i thought about doing this by vectors, but you need more info to do this.
are you CERTAIN these problems don't involve right triangles?
i can see how you could do this if you put it onto graph paper, and assign units, and use a protractor. what is the name of this class? trig? there are other ways to do this if i know where its coming from.

They're not, or it would of specified it...unless they screwed up, what would the answer be if it was? any of the multiple choice answers? (on the first one, 2nd one got cut off)

I'm pretty sure theres a way to just solve this using a calculator, on several other problems i'm getting tan 55 = x/40 ....this is why I didn't become a math teacher :P

on the back of a piece of scrap paper i have here (so im sure they're wrong)
i have:
<a=36
<b=100.7
<c=43.3
A=45
B=48
C=66
found the angles using tan first from <a. then flipped the paper upside down because i figured that segment AC was the hypotenuse. used the pythagorean theorem on A=45 B=X and C=hyp=66.
48^2 + X = 66^2
2304 +X =4356
x^2=2052
x=45.29
****, i typed in the wrong one, that wasn't the piece of paper with the right answer on it
sorry, im trying to do two things at once. i guess you'll have to wait for somebody with a brain to do it.
