How do I find X in this triangle?

Question

anonymous · Answer

This triangle...

anonymous · Answer

I am not looking for an answer I just want to know how to do this problem.

anonymous · Answer

Hint: use sine of 45 degrees

anonymous · Answer

Remember, sine is opposite over hypotenuse

anonymous · Answer

Sorry but I am not familiar with the term sine. I have not learned that yet.

anonymous · Answer

Exlain?

anonymous · Answer

Have you studied trigonometry?

anonymous · Answer

No, I am in geometry right now.

anonymous · Answer

Hmmm...

calculusxy · Answer

You wanna look for the missing side lengths that you wanna find. The misiing side lengths are in here asps of the hypotenuse and the adjacents. Since we know that that is the cosine, we can write something like cos(60)=adjacent/hypotenuse=x / 4

U wanna now plug that into ur calculator and whatever the cos will equal to that will be multipled by 4 to get u what x equals to.

I know so its a right isosceles triangle , right..

nikato · Answer

And there's a a theorem that says if the two congruent sides are lets say a

nikato · Answer

Then the base is "a " root 2

calculusxy · Answer

But I think that using trignometry is the easiest way to find ur answer

anonymous · Answer

How do I find the answer using geometry?

calculusxy · Answer

I don't have any idea except for geometry :) I would keep trig as a shorthand method. I mean if you can grasp it, them there u go!

anonymous · Answer

I think @nikato might have the best way for @asher1027

nikato · Answer

So using that theorem and think x=4 root 2

nikato · Answer

That's a geometry theorem^ just letting u know

calculusxy · Answer

There is sine cosine and tangent . So each have formulas. I can't give u each description cuz I really don't know what they means Ina triangle.

anonymous · Answer

I'm sorry but I am lost. :/ @nikato Do you mean x=4^2?

nikato · Answer

No, 4 square root of 2

nikato · Answer

Btw, just asking are u in public school?

anonymous · Answer

No I am home schooled.

anonymous · Answer

@asher1027 Really? I was homeschooled too!

anonymous · Answer

@HomeschoolGrad Nice! ( ͡° ͜ʖ ͡°)

anonymous · Answer

@HomeschoolGrad I kind of figured that out due to your name. haha

nikato · Answer

Haha^ @asher1027 do you get it now?

anonymous · Answer

lol

anonymous · Answer

Yes I believe I do. @nikato So would I be correct in saying that 4 √(2) is my answer?

nikato · Answer

Yes

anonymous · Answer

Awesome. Thanks!
