ik:P how did u get those answers?

- anonymous

well x was half of the hypotenuse and you times x by the square root of 3.

- anonymous

to get y

- anonymous

oohh ok.. wb Y?

- anonymous

i dont know what that means

- anonymous

what bout Y? how did u get Y?

- anonymous

hah sorry..:/

- anonymous

ooh i mean X.. how do u get X? cuz that was for Y right?

- zpupster

that answer is wrong becasue when you have a 90-45-45 triangle
the other sides are always equal.

- anonymous

oh, oops, i thought is was a 30-60-90 triangle sorry

- anonymous

so how do u do a 90 - 45 - 45 triangle?

- anonymous

ik that y would be 15 sqrt of 2.. but how do i find X?

- zpupster

no
x and y will be the same

- anonymous

really? ooh.. how do u find it?

- zpupster

A= unknown angle, b =known angle 45 and c = 90
sinB =AC/AB=Opp/hyp

- zpupster

AC = AB x sinB

- anonymous

then i just substitute in?

- anonymous

u lost me...:/

- zpupster

label the angles in the drawing first

- anonymous

what drawing? mine?

- zpupster

yes

- anonymous

sup im back what did i miss?

- anonymous

umm.. confusing stuff.. that i dont get..

- 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

thats what it says for a 45-45-90 triangle

- anonymous

really?! thaaanksss:D

- anonymous

your welcome, glad to help.

- anonymous

but how did u get 15?

- zpupster

15 is indeed the answer, but did you see how it was calculated

- 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

no..

- zpupster

AB is the hyp or 15sprt2

- zpupster

did u get that part

- zpupster

what part are u missing

- anonymous

oh nvm.. i guess im not..thaaanks:)

- zpupster

anothr time then later
