Really stuck on maths, can somone help please?
In triangle KLM, angle LKM = 45degrees and angle LMK = 30degrees. Find the exact value of LM/KL.

Yeah I think so.

Yes probably. I have no idea.

But he didn't tell us..
Angle or side?

I'd just do it the way Tribute did it. No point doing it using trig or stuff like that if you can do it like that which is perfectly acceptable and gets you the answer....Then again if that is the wrong answer you probably do need to use trig heh.
Is this using the sine and/or cosine rule by any chance?
sideLM divided by sideKL

Isn;t LM/KL a side or an angle

I think he has to show it using trigonometry.
Triangle = 180 degrees
180 - (45+30) = 105 degrees
Is that okay?
180 - (45+30) = 105 degrees
Is that okay?
Heh, if you asked me two years ago i could probably do this, thankfully after so long without maths i have been able to cleanse its principles from my fleshy brain tissue.
