ik:P how did u get those answers?
anonymous
  • anonymous
well x was half of the hypotenuse and you times x by the square root of 3.
anonymous
  • anonymous
to get y
anonymous
  • anonymous
oohh ok.. wb Y?
anonymous
  • anonymous
i dont know what that means
anonymous
  • anonymous
what bout Y? how did u get Y?
anonymous
  • anonymous
hah sorry..:/
anonymous
  • anonymous
ooh i mean X.. how do u get X? cuz that was for Y right?
zpupster
  • zpupster
that answer is wrong becasue when you have a 90-45-45 triangle the other sides are always equal.
anonymous
  • anonymous
oh, oops, i thought is was a 30-60-90 triangle sorry
anonymous
  • anonymous
so how do u do a 90 - 45 - 45 triangle?
anonymous
  • anonymous
ik that y would be 15 sqrt of 2.. but how do i find X?
zpupster
  • zpupster
no x and y will be the same
anonymous
  • anonymous
really? ooh.. how do u find it?
zpupster
  • zpupster
A= unknown angle, b =known angle 45 and c = 90 sinB =AC/AB=Opp/hyp
zpupster
  • zpupster
AC = AB x sinB
anonymous
  • anonymous
then i just substitute in?
anonymous
  • anonymous
u lost me...:/
zpupster
  • zpupster
label the angles in the drawing first
anonymous
  • anonymous
what drawing? mine?
zpupster
  • zpupster
yes
anonymous
  • anonymous
sup im back what did i miss?
anonymous
  • anonymous
umm.. confusing stuff.. that i dont get..
anonymous
  • anonymous
oh well on my reference sheet it says the hypotenuse is equal to x to the square root of 2 and the other two sides are x, so i guess both x and y =15
anonymous
  • anonymous
thats what it says for a 45-45-90 triangle
anonymous
  • anonymous
really?! thaaanksss:D
anonymous
  • anonymous
your welcome, glad to help.
anonymous
  • anonymous
but how did u get 15?
zpupster
  • zpupster
15 is indeed the answer, but did you see how it was calculated
zpupster
  • zpupster
the sides you are looking for are AC or BC C being the right angle the def of the sine of and angle is OPP/ hyp
anonymous
  • anonymous
no..
zpupster
  • zpupster
AB is the hyp or 15sprt2
zpupster
  • zpupster
did u get that part
zpupster
  • zpupster
what part are u missing
anonymous
  • anonymous
oh nvm.. i guess im not..thaaanks:)
zpupster
  • zpupster
anothr time then later
