Aclock is constructed using a regular polygon with 60 sides. the polygon rotates every minute. how much has the polygon rotated after 7 minutes? 14° 21° 35° 42°

Hello!

A polygon with 60 sides is very much like a circle. One full rotation around a circle is 360°. In our case we have 60 sides, or 60 minutes, meaning it rotates 6° per minute.

Now we just multiply our degrees.

6°(7 minutes)=42°.

Our final answer is 42°

I hope this helps!

There are 360 degrees in a full rotation. So, we need to divide 360 degrees by 60 because the polygon/clock has 60 sides. 360/60 is 6, right? Each minute, it moves 6 degrees. But, this is just for one minute. We need to find out for 7 minutes. So, we need to scale it with multiplication. 6*7= 42. So, after 7 minutes, it will revolve 42 degrees. Hope this helped!
