The first figure which contain angle g ,Is it a right angle ?
anonymous
  • anonymous
yes
anonymous
  • anonymous
it should be |dw:1365471862587:dw| Anyway ,Since this is a right angle triangle then Use Sine, Cosine or Tangent . Where Sin=opp/Hyp. Cos=adj/hyp. tan=opp/adj You got it ?
anonymous
  • anonymous
yes i understand
anonymous
  • anonymous
Great,Can you deduce the value of g ?
anonymous
  • anonymous
would it be 10
anonymous
  • anonymous
How did you get that ?
anonymous
  • anonymous
idk lol would it be 20/10=2?
anonymous
  • anonymous
you are calculating the coefficient of g which is an angle Since you were given the Opp and the hypo. ,Therefore you will use the sin Sin(g)=10/20= ?
anonymous
  • anonymous
sin(q)=0.5
anonymous
  • anonymous
Nope, You need to get the angle Sin^-1=10/20= ?
anonymous
  • anonymous
i don't understand
anonymous
  • anonymous
If Sin(a)=1 and you need to get the coefficient of a ,how To get a ? Type on your calculator Shift+Sin+1 and the result will be the coefficient of a . Can you follow the steps ?
anonymous
  • anonymous
ok igot 0.017
anonymous
  • anonymous
Ugh,No that;s wrong . Check this http://www.picalc.com Type : asin(10/20)= ?
anonymous
  • anonymous
soryy i got a pelletty caculater,,,i got 30
anonymous
  • anonymous
Thats the Right answer :'')
anonymous
  • anonymous
ok so g=30 lol
anonymous
  • anonymous
Yes *cry out of happiness*
anonymous
  • anonymous
Yay!lol so then is i=60?
anonymous
  • anonymous
i is an angle in another figure ! not this figure right ?
anonymous
  • anonymous
yup but its not a angle i drew it
anonymous
  • anonymous
In the other Triangle Do the same Steps (sin,cos,tan) And notice that : That median cut the line to two equal parts (The same length)

@ryan123345 :May you continue ,Because i want to drink something +_+ ...
ryan123345
  • ryan123345
lol
anonymous
  • anonymous
ok ^ ?
ryan123345
  • ryan123345
Well I rather explain it to her from the begining
anonymous
  • anonymous
so can u help me plezz! :)
anonymous
  • anonymous
S U R E . @heather040200 : he will explain to you from the beginning :D Enjoy ! and i will check it later just in case ^_~
ryan123345
  • ryan123345
Ill help :)
ryan123345
  • ryan123345
\[\cos (g)=\frac{ 10 }{ 20 }\]
anonymous
  • anonymous
kkk so i got 30
ryan123345
  • ryan123345
\[g=(\frac{ 1 }{ 2 }) \cos^{-1} \]
anonymous
  • anonymous
so 15?
ryan123345
  • ryan123345
@Eyad fan me so i can message u
anonymous
  • anonymous
HELLO is my answer right??
ryan123345
  • ryan123345
its not 30
anonymous
  • anonymous
is it 15
ryan123345
  • ryan123345
try plugging in equation I wrote with the cos
ryan123345
  • ryan123345
to the calculator
anonymous
  • anonymous
i got 60
ryan123345
  • ryan123345
Good Job. so now you know that g is 60 deg
anonymous
  • anonymous
ok so now how do we get i
ryan123345
  • ryan123345
i is a degree or a side i cant really tell
anonymous
  • anonymous
side
anonymous
  • anonymous
so cos=20/10 =60
ryan123345
  • ryan123345
ok so now since you know that the |dw:1365476272169:dw|
anonymous
  • anonymous
|dw:1365474950733:dw|
anonymous
  • anonymous
J is just the brown triangle you have in your pic
ryan123345
  • ryan123345
|dw:1365476405488:dw|
anonymous
  • anonymous
so is i=sqrt.3
ryan123345
  • ryan123345
yes :)
anonymous
  • anonymous
ok so now how do we get j |dw:1365482366945:dw|
ryan123345
  • ryan123345
|dw:1365476773129:dw|
anonymous
  • anonymous
sqrt9
ryan123345
  • ryan123345
which is? :)
anonymous
  • anonymous
3 is the answer
ryan123345
  • ryan123345
Good Job :)
anonymous
  • anonymous
thank you so much for your help :)
ryan123345
  • ryan123345
No problem. I'm always here :)
