Answer:
Correct choice is D
Step-by-step explanation:
Consider regular 60 sided polygon (regular means all sides are of equal length). Connect the center of this polygon with each polygon's vertex. You get 60 equal isosceles triangles with base that is polygon's side. The measure of the angle opposite to the base is
Rotating the polygon by 6° over the center, each such triangle will map onto the previous triangle. Thus, the least angle by which a regular 60-gon can be rotated so that it maps onto itself is 6°.

Answer:
13.5 hours
Step-by-step explanation:
If it takes Amy 12 hours to complete the job alone
And it takes Tom 15 hours to complete the same job alone,
How long will it take for both of them to get the job done together?
Amy= 12 hours
Tom= 15 hours
Amy + John =?
(12 + 15)/ 2
27/2= 13.5 hours.
So it would take Amy and Tom 13.5 hours to complete the job together.
