Start by drawing it on a graph.
Put x along the bottom and y up the side.
Now draw a line at 67 deg above the X axis (this is the normal convention)

For a point1 unit along the diagonal line draw lines down to the X and across to the Y axis - now use normal trig stuff (sin/cos) for these two triangles
