Depends what you mean by better. The 17 degree deadrise will cut through the waves better than the 21. However the 21 will plane faster and will be more stable at rest. So better is dependant on the use you are planning.
To cut plexiglass you should use a handsaw and make sure it is a handsaw that can cut in straight lines. You should also measure out how you much you need and what shape you need.
Suppose the top face of the pyramid is ABCD with the square EFGH directly below it.Suppose AC and BD meet at P, the apex of the pyramid.Make a cut with a plane through P which is parallel to AB and goes through EF.Make a cut with a plane through P which is parallel to BC and goes through FG.Make a cut with a plane through P which is parallel to CD and goes through GH.Make a cut with a plane through P which is parallel to DA and goes through HE.The result will be the square-based pyramid PEFGH.
Cut it in half through its centre. Then cut each half into half. You will have four fourths.
Cut the square into two. Put one part on top of the other. Cut through both parts with your second slice. Stack the pair of slices on top of the other. Cut through all four with the third cut.

The ship's prow cut easily through the waves.
surface waves can only travel along the surface.
When waves cut completely through a headland, a feature called a sea cave is formed. Sea caves are formed by the relentless erosion of waves gradually wearing away the weaker rock layers of a headland. Over time, the waves create openings and cavities that can extend deep into the headland.
Seismology includes study of waves. The propagation of waves is studied through the use of Mathematics and physics, and the concept is extended to Seismic waves.
How do scientists use seismic waves to study the Earth
sound waves can not travel through space since they use the air around us to move.
Use cut on it.
It can learn it through the use of the Cut HM.
mechanical waves need a medium to travel through, electromagnetic waves do not. Electromagnetic waves can travel through space, mechanical waves can not.:PElectromagnetic waves do not require a medium, but mechanical waves do.
