Question
Is it possible to have a regular polygon whose each exterior angle is: 40° of a right angle.

Solution
Let the number of sides = n
Each exterior angle = 40% of a right angle
`= 40/100 xx 90`
= 36°
n = `360^circ/36^circ`
n = 10
Which is a whole number.
Hence it is possible to have a regular polygon whose exterior angle is 40% of the right angle.
