I really don't know where must I ask this Q :(

[Kazeon]

Please, open the thumbnail I've attached below..

Can someone show me how to find dat X, I mean, not visually find dat X?

wait, I forgot the letter after b

answer

cos(x) = a/d
sin(x) = b/d
tan(x) = b/a
hence,
x = acos(a/d)
x = asin(b/d)
x = atan(b/a)

do you mean the angle?

 

[Kazeon]

yes!!

that square part is 90*. you know what I mean

 

[Menag]

Should be
cos(x) = b/c
sin(x) = a/c
tan(x) = a/b
hence,
x = acos(b/c)
x = asin(a/c)
x = atan(a/b)

I hope I didn't make a mistake.

 

[Kazeon]

I will try it!! thnk for help

Just translating it to your triangle, so nothing gets mixed up^^:

cos(x) = a/d
sin(x) = b/d
tan(x) = b/a
hence,
x = acos(a/d)
x = asin(b/d)
x = atan(b/a)

 

[Kazeon]

lol
thnks anyway!

 

[Menag]

oh, I just saw a and b and thought the last one would be c. Sorry for that^^

well, normally you denote the hypotenuse as C
