that is where i started getting confused....

^^that
jdoe0001

what that means is just that the longest side is TWICE as much as the smallest side so "2a" is twice as much as "a" so if I had a 30-60-90 triangle whose smallest side were say 25 then the longest will be TWICE as much, or 50, thus |dw:1375658213907:dw|

if I had a 30-60-90 triangle whose smallest side were say "WHATEVER" my longest side will be "WHATEVER" x 2
jdoe0001
  • jdoe0001
still confused?
highschoolmom2010
  • highschoolmom2010
not on the 2a part but what about the a sqrt3
anonymous
  • anonymous
you just have to multipy the 20 with the sqrt of 3.
anonymous
  • anonymous
first, you have to divide 40 by 2, in order to find a. cos its 2a/2 > you will now find a. and then there it says "a sqrt of 3", so you just have to multiply a with sqrt of 3.

  • anonymous
do u get it? :)

btw, this video goes over 45-45-90 and 30-60-90 triangles. These videos are helpful
highschoolmom2010
  • highschoolmom2010
i have never used any terms relating to trig so no i dont really get it :( @phi what video??
phi
  • phi
this one http://www.khanacademy.org/math/geometry/right_triangles_topic/special_right_triangles/v/intro-to-30-60-90-triangles
highschoolmom2010
  • highschoolmom2010
oh ok ill watch it
anonymous
  • anonymous
@highschoolmom2010 got the answer?
highschoolmom2010
  • highschoolmom2010
nope not even close
anonymous
  • anonymous
ok...you want to find x and y..right?
anonymous
  • anonymous
You know about trigonometry ratios?
highschoolmom2010
  • highschoolmom2010
yea.. i tried to do it and was told it was wrong so i got confused nope im in geometry
highschoolmom2010
  • highschoolmom2010
@phi it kinda helped me figure that sqrt 3 part bu tnot how to do the problem
anonymous
  • anonymous
|dw:1375807850273:dw|
phi
  • phi
in that case watch the video where he does examples
anonymous
  • anonymous
or we can go using geometry
highschoolmom2010
  • highschoolmom2010
that would help better
anonymous
  • anonymous
ok
anonymous
  • anonymous
this is a 30-60-90 triangle
anonymous
  • anonymous
|dw:1375808252038:dw|
anonymous
  • anonymous
this means BC is AB*root 3
anonymous
  • anonymous
and AC is AB*2
anonymous
  • anonymous
okay?
highschoolmom2010
  • highschoolmom2010
ok
anonymous
  • anonymous
so BC=root3 *(x) =y
anonymous
  • anonymous
and AC=x(*2)=40
highschoolmom2010
  • highschoolmom2010
can u draw what u are saying im *more visual*
anonymous
  • anonymous
|dw:1375808671220:dw|
anonymous
  • anonymous
from this x=20 and put that x to find y
highschoolmom2010
  • highschoolmom2010
|dw:1375808797534:dw|
anonymous
  • anonymous
yes
highschoolmom2010
  • highschoolmom2010
like that ????
anonymous
  • anonymous
yes...you got it
highschoolmom2010
  • highschoolmom2010
so so what now....
anonymous
  • anonymous
x=20 and y=20 root3
highschoolmom2010
  • highschoolmom2010
HOLY COW I DID IT :DDDDD
anonymous
  • anonymous
hmm...Congrats....:D
