heres how i found the 3rd angle (x), in radians:

$\displaystyle

\frac{1}{8} \pi = 22.5°$

so angle is $\displaystyle 90°- 22.5° = 67.5°$

$\displaystyle sin22.5 = \frac {5}{x} , so x = \frac {5}{sin22.5} = 13.06° $ or .228 radians

Is this right, and how could i find the answer to my question without converting to degrees?

More over how could i find the length of the other two sides?

Thanks
