well i didnt know you wanted me to find that :(

Answer 16

That is the definition of cosine

Answer 17

So now, apply it to your triangle.

i knew that but how do i use cosine to solve this triangle

Answer 19

What is the acute angle that you know?

Answer 20

24

cosine of 24?

Answer 22

What is the side adjacent to that angle?

Answer 23

11

Answer 24

cos(24) = 11/x

Answer 25

Solve that.

Answer 26

Yep.

Answer 27

That was pretty easy, wasn't it?

Answer 28

thank you so much :D
the only problem is that this is what happens EVERY time i have an advanced math problem is that i have to relearn it every time

Answer 29

The key is practice. You don't have to relearn your name every day do you? That's because you have been over it and over it until now you know it automatically and will never forget it.

Answer 30

well, my mom sent me to remedial math classes and they made me repeat over and over and it didnt work :( i started not learning things around 11 or so and the remedial class gave up on me and suggested a special education and pills for depression anxiety. what is special education

Answer 31

It is classes for people with learning disabilities. If I were you, I would take charge of my own self and start learning what you are supposed to learn and quit listening to all these people who are telling you that you need medicine and are depressed and all that phsycobabble.

Answer 32

medicine didnt work, i try learning what im supposed to i study for at least 4 hours at a time

Answer 33

Well you can obviously learn because you know how to write sentences and spell words. So don't give up on yourself and don't let others define who you are.

Answer 34

And quit studying for 4 hours at a time without a break.

Answer 35

i dont know because my doctor said that i "stopped" learning when i was 11 how does a person stop learning

Answer 36

then how do i study the right way

Answer 37

Did you stop learning?

Answer 38

How old are you now?

Answer 39

i cant really say how old i am lets say around 19-21

Answer 40

Have you learned anything in the last 10 years?

Answer 41

well all i "learned" is what i have to deal with all the time im forgetful and feel stupid and i always am sad about nothing

Answer 42

Do you drive a car?

Answer 43

your right i DID learn to drive a car o_- but i learned to drive a car when i was little (on our driveway and my father told me the road signs and things) weird..

Answer 44

No one learns to drive in a driveway. You have to drive on a road to learn to drive.

Answer 45

well i dont know then :( the doctors cant figure out whats wrong i hate the doctors, we stopped going years ago.

Answer 46

There's nothing wrong. Get that out of your head and get on with your life.

Answer 47

well how do i learn school things, im still in hs :(

Answer 48

i try to get on with my life but its so hard. is there something i can do to help this? i tried every remedial class in the book but i am stuck relearning things over and over

Answer 49

By doing all the stuff your teachers assign and more if that's what it takes to master the material. Quit focusing on learning every little thing and start trying to master the material. If you want to play the piano, it's not enough just to learn the notes. You have to master the music. Take that approach to your studies. And yes, life is hard. It was not advertised as easy.

Answer 50

i can play the piano, i can't learn geometry and algebra. i tried tutors and books and the internet and i hardly get anything out of it ever. i only learn a little bit of anything and then nothing else its like my brain is full of nothing

Answer 51

Stop telling yourself that it is hopeless. Sounds like you're trying to make it a self fulfilling prophecy. Quit feeding yourself all those negative thoughts. Find Jesus. He will help you.

Answer 52

I would but theres a reason i cant do that -_-

Answer 53

There is NO reason you can't do that. Seek and you shall find.
