@maxromeo are you just saying that because thats what i said?
im pretty sure thats right
you need to use tan so you have tan(30) = x/11 which is the same as 11tan(30) do it in calculator
maxromeo that is wrong
ivette is right.
u can also use sine rule
30-60-90 rule http://upload.wikimedia.org/wikipedia/commons/4/45/30-60-90_triangle.jpg
sin rule won't work because you don't need hypothenus and you don't have the opposite side
i used the 30-60-90 rule i got 6.35
i also get 6.35 using sine rule
Since you are given the adjacent side of the angle of measure 30, you can use the trigonometric ratio: tan 30 = x/11 because the tan function of an angle is the opposite side over the adjacent side. So, x = (11)[tan(30)] -> (11)[sqrt(3)] / 3 Answer is C
is that coincidence? or is it correct? @ivettef365
Good luck to you in all of your studies, and thx for the recognition! @phknkayy
@ivettef365 ...why cant the sine rule be used??
How did you get to 6.35, with sin, how did you calculate?
sin = opp/hyp you don't have the opposite neither the hyp
Oh, I see you use the 60, that is ok
@tcarroll010 thank you
but still you need the x and that won't help
anyone know the interior angle rule?
oh ....11/sin60 X sin30= 6.35
uw! btw, the sine rule is also ok for finding the measure. One may or may not consider that a little more bulky since you have to use 2 trig ratios instead of one. But either method is fine.
@tcarroll010 .. thanks 4 verifying my method
what does uw stand for?
