Question

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

Answer 1

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.
