I think there is something wrong with the calculator with solving equations with variables. I put in:

sin(45)/22=sin(63)/x


It came up with: x=4.326959873244858
The real answer is: x= about 27.7

please see into this problem

when you type in you problem, be careful that you close the parenthesis : Sin 63/22 and Sin (63)/22 are two different numbers. your equation should look like this: x= (Sin 63) x 22 / (Sin 45)

i like to add extra parenthesis just so i know my answer will be correct.

[input]sin(45)/22=sin(63)/x[/input]

I think your problem might be the result is in rad instead of deg. (because our solver is currently only able to solve in rad)

sin(45)/22=sin(63)/x
x*sin(45)/22=sin(63)
x*sin(45)=sin(63)*22
x=sin(63)*22/sin(45)

in degrees:
[input]sin(63)*22/sin(45)[/input]

in rad:
[inputrad]sin(63)*22/sin(45)[/inputrad]
