How to cutout a angle in 3d extrusion

[digitalhomeserviceswa]

Hi all, I'm having trouble cutting out an angled shape in a 3d extrusion. I created a shape in the sketch (3d) that has an angle and then performed an extrusion. Now on that angle that's now a 3d block, I want to again create an angle that I want to cutout of the 3d block. I place a new ketch plane where I want to draw the angle and then extrude (cutout) on that plane but each time I do so it's not following my angle. It always cuts out at  90 degrees from the drawn line. 

I'm stuck. Hope someone can help me.
