One angle of a regular polygon is `168^(circ)`. How many sides dóes it have?

Explanation

If one outer angle be `6^(circ)`, then the number of sides `=360^(circ)/6=60 .` This is a whole nümber. That is `360^(circ)` is the multiple of 6 .

Therefore we can draw-a regular polygon with each outer angle `6^(circ) .`
What about `7^(circ) ?`
360 is nót a multiple of `7^(circ)`. So, we cảnnọt draw a regulảr polygon with .each angle `7^(circ)`.
