Any angle that you like. There are no constraints on a single angle of a decagon, only on their sum.
90 degree angle is the measure of each piece. Once the angles are formed at 145 degrees, each corner makes a 90 degree angle.
35 degrees

There is too much extra needed information before an answer can be given. Is the wood to make only the circumference, or would it make all the surface, what is the width of the wood, what design to make the octagon.
wood is not a proper noun
Each exterior angle is 45 degrees (interior angle = 135 degrees).
8 degree hardwood 11 degree soft wood with a degree to play with
to make an quilateral hexagon (all the angles identical) each internal angle should be 108 degrees.
a protractor
When you say "crown cut" I think you are referring to a compound angle cut. A compound angle is 2 angles cut at the same time. In crown for instance you put the trim in the saw at a 45 degree angle, and tilt your saw blade at a 45 degree angle as well.
A miter saw. A skill saw will do it with some practice.
90 degree angle is the measure of each piece. Once the angles are formed at 145 degrees, each corner makes a 90 degree angle.
Cut a paintbrush at a 45 degree angle and the tip should be very thin. You can make it shorter by cutting the end of the wooden handle and putting blu tack or something at the end instead of smoothing the rough wood out. Hope this helps.
It is 22.7 ft, approx.And the word is piece, not peice.
The wood formed an acute angle with the wall.
You need a miter saw. It has a back gauge to butt the wood up to, and then the saw has holders to keep it from wobbling. You can set the angle. It may just have notches for 90 degrees and 45, or it may have a protractor on it.
The fact that plywood consists of fibers ("the grain of the wood") that are laminated in successive layers orthogonal to one another (i.e., at a 90 degree angle) gives it tremendous structural strength - much higher than a wood product where all of the fibers are aligned in parallel (as in ordinary wood).
