Now to get the angle, cos T = p . q / |p||q|
|p| = |q| = sqrt( 500x500 + 145x145 ) so |p||q| = 500x500 + 145x145 = 271025
so cos T = 197802 / 271025 = 0.72983
so T = 43.128 degrees.
isn't that the dot product ? https://en.wikipedia.org/wiki/Dot_product.....and find their cross product......
The cross product is .....
z vertically ?....x and y in the horizontal plane and y vertically.
A hollow octagonal pyramid is my guess, but it is going to look like a spike, I think. Presumably the OP is going to stick it on top of some more 'roof' (unless it's part of a model).(Would love to know what you’re actually making!)
You have it right I think for the saw tilt angle, but how would you calculate the mitre cut angle?
Some typos:
