not a task for a novice unless.....
As an experienced woodworker I would use a router and sled, tipping the board at the appropriate angle. The width of 22 cm coverts to 8.66 inches, is beyond the resaw capacity of all but the largest bandsaws. But that would be an easy solution if you have access to one.
You could make a series of cross cuts on the table saw with the board held in a jig at the appropriate angle and knock out the waste in between. Then plane the surface smooth with a hand plane. You could do the same with a hand held circular saw, adjusting the depth of cut vfor each succeeding cross cut which correspond to the angle.
The answer to your question will only be as detailed and specific as the question is detailed and specific. Good questions also include a sketch or a photo that illustrates your issue. (:< D)
