Answer 2

It's a Right Triangle? Have you considered the Pythagorean Theorem?

Answer 3

I have used the Pyhagorean Theorem to find line ML, but I must find angle K and angle L, which I do not understand how to do ):

Answer 4

Excellent. What was the length of the missing side?

Notice, please, that you could have shown your work and provided some discussion up front. Talking is very helpful!

Answer 5

I'm sorry about that. I have found that line ML = 4.5
I have been told by my teacher that to find the missing angles, the trig table must be used. an example would go something like this: http://images.classwell.com/ebooks/images/mcd_geo/mcd_ma_geo_lsn_0395937779_p567_f09.gif

Answer 6

I do not understand trig that well. I'm having a hard time finding angle K and angle L ):

Answer 7

Yes, that should do it. Sometimes, you just have to memorize it.

The cosine of an angle is Adjacent / Hypotenuse. Use that.
The sine of an angle is Opposite / Hypotenuse. Use that.

Answer 8

in this case, to find angle K I would use cos(K)= Adj/Hyp?

Answer 9

I understand now, thank you!

Answer 10

bear in mind that the adjacent for K is not the adjacent for L or M, same goes for the Opposite side :)

Good call, @jdoe00001 I was actually thinking of just that warning but managed to forget before I hit the [Post] button.
