We are asked to solve for the angle of rotational symmetry of a given regular polygon and the formula is degrees of rotation = 360° / number of sides. In this problem, the solution is shown below:
We used n = 5 since pentagon has five number of sides
degrees of rotation = 360° / 5
degrees of rotation = 72°

The answer is the third in the choices 72°.

How would you measure the volume of a brick that contains holes

vaieri [72.5K]

In order to measure the volume of a brick that contains holes, what you need to do is to get the volume of both the brick as a whole, and the volume of the holes. Once you have the volume, you subtract the volume of the holes to the volume of the brick. The final answer would be the volume of a brick that contains holes. Hope this helps!
