To the nearest degree, what is the measure of each exterior angle of a regular 11-gon?

The measure of each exterior angle of a regular 11-gon to the nearest degree is:

                                      33°

A regular n-gon is a polygon whose measure of all the sides and all the angles are equal i.e. it is a equilateral and equiangular polygon.

We know that the measure of each exterior angle of a regular n-gon is given by:

We have:

n=11

Hence, the measure of each exterior angle is given by:

Hence, to the nearest degree the measure of the exterior angle is: 33°

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.
