We aren't going to tell you the answer, only how to solve the question.

I don't know how to solve the problem though.

0.8 100% ;)

thanks alirezamemarian!

alirezamemarian you should read the Code of Conduct :)

The way I see it the figure is drawn to scale...then Diyadiya's answer should help you further.

  • inkyvoyd
Nice job giving him the answer, but are you going to do that for the rest of his life?
inkyvoyd
  • inkyvoyd
That's why we teach people how to do things instead of give them the answer.
anonymous
  • anonymous
to all! ok yes! sorry! it`s better that we show the way of solve,not give them the answer,yes? :)
Diyadiya
  • Diyadiya
yes :)
anonymous
  • anonymous
I agree that someone should of showed me how, but No One did.
Diyadiya
  • Diyadiya
We were trying to show you ,But someone just gave you the final answer and you were happy with it If you want to know how i can help you :)

  • anonymous
and @ inkyvoyd - I am a girl. :)
anonymous
  • anonymous
I would love to know how.

I didn't want @ali to think I didn't appreciate their help.

ok \[CosC= \frac{adjacent \ side}{hypotenuse} \] Do you know which is adjacent side and hypotenuse ?
anonymous
  • anonymous
yes I do.
Diyadiya
  • Diyadiya
So what do you get now ?
anonymous
  • anonymous
what do you mean?
Diyadiya
  • Diyadiya
\[CosC= \frac{adjacent \ side}{hypotenuse}\] To find Cos we divide adjacent side by Hypotenuse Which is adjacent side and hypotenuse in the figure ?
anonymous
  • anonymous
The hypotenuse is the AC line and the adjacent sides are the other sides AB and BC
Diyadiya
  • Diyadiya
Okay Hypotenuse is AC and value of AC is also given in the fig which is 90 Here since we are finding Cos C , adjacent side is the side adjacent to angle C ,Which is BC and value of BC is 72
anonymous
  • anonymous
okay
Diyadiya
  • Diyadiya
Now can you find CosC ? just divide adjacent side by hypotenuse
Diyadiya
  • Diyadiya
thats is \[\frac{BC}{AC}\]
anonymous
  • anonymous
so it would be 0.8? 72/90
Diyadiya
  • Diyadiya
Yes ! Right :)
anonymous
  • anonymous
thanks. i didn't know it was that simple. I couldn't find out how to do it in my book. Thanks for showing me how to do it.
Diyadiya
  • Diyadiya
Glad to help :) and you can keep this in mind while doing these kind of problem Sine is Opposite over Hypotenuse Cosine is Adjacent over Hypotenuse Tangent is Opposite over Adjacent
anonymous
  • anonymous
okay thanks for the help!! ;)
Diyadiya
  • Diyadiya
Anytime :)
