Answer:
154.285
Step-by-step explanation:
The sum of the interior angles of a 14-gon = (14-2)*180 = 2,160 degrees. There are 14 vertexes (vertices) for a 14-gon. It is 'regular' so all these angles are equal. By dividing 2160 (sum of all angles) by 14 (total amount of angles) we can see how much each angle is worth. So the interior angle of each is 154.285 degrees.
Answer: 3 mi/h
Step-by-step explanation:
Here we have to find the speed 
at which Sarah walks to school, knowing the distance 
she has walked and the time 
she expends.
So, in this case we can use the following equation:
Where:
Solving:
This is Sarah's speed
