Question

A ceiling fan has five equally spaced blades find the angle of rotation the Maps one blade on to the adjacent blade

Answer 1

A rotation of 72 degrees will map one blade of ceiling fan to its adjacent blade.

Explanation:

We are told that a ceiling fan has 5 equally spaced blades. It will work as a regular pentagon.

We can find angle of rotation to map one blade on adjacent blade dividing 360 by 5 as sum of angles of regular pentagon equals to 360 degrees.

`\text{ Angle of rotation}=(360)/(5)`

Upon dividing 360 by 5 we will get,

`(360)/(5) =72`

Therefore, a rotation of 72 degrees will map one blade of ceiling fan to its adjacent blade.
