This result is known as Cramér's decomposition theorem, and is equivalent to saying that the convolution of two distributions is normal if and only if both are normal. Cramér's theorem implies that a linear combination of independent non-Gaussian variables will never have an exactly normal distribution, although it may approach it arbitrarily ...
This is, in fact, the origin of the specification above that x be a regular sexagesimal fraction: choosing x in this way ensures that both x and 1/x have finite sexagesimal representations. To engineer a problem with a nice answer, the problem setter would simply need to choose such an x and let the initial datum c equal x − 1/x.

An industrial electric motor . An electric motor is a machine that converts electrical energy into mechanical energy.Most electric motors operate through the interaction between the motor's magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor's shaft.
