A regular decagon has 10 sides. How many reflectional symmetries does a regular decagon have?
lina2011 [118]

The rule for regular polygons are very easy. The number of reflectional symmetries is same as the number of sides. Regular polygons have all sides the same length and all angles same. Reflection symmetry means that you can fold the shape along that line and it will match up.

For this question, we want the number of reflectional symmetries of a regular decagon. Decagon is a 10 sided figure. Hence, the number of reflectional symmetries is 10.

There are 5 symmetry lines from one vertex to opposite vertex and 5 more symmetry lines form midpoint of one side to midpoint of opposite side.

Find the volume of 20m, 5m, 18m
HACTEHA [7]

Answer:

600 m³

Step-by-step explanation:

The shape we have is a rectangular pyramid:

Formula:<u><em> (volume of a rectangular pyramid)</em></u>

Volume = (1/3) × Base Area × height

___________________________

In our case :

Base area = L × W = 20 × 18 = 360 m²

height = 5 m

⇒ Volume = (1/3) × Base Area × height

    \Longrightarrow \text{volume} \  =\  \frac{1}{3} \times 360\times 5

\Longrightarrow \  \text{volume} \  =\  600\  m^{3}

Contact [7]

Answer:

1. The nature of creative work is that it can take almost any form, so the scope of the copyright law was drafted in such a way to take that into account. The categories that works can potentially be protected in are so wide that it’s difficult to imagine what types of creative work are not protected.

2.Some artists look for ways to extend copyright for longer than the laws normally allow. Why do they do this?

3.The Benefits of Using a Creative Commons License Numerous high-profile authors (including futurist Cory Doctorow), artists, musicians (such as the rock band Nine Inch Nails), and even government agencies and entities (including the White House) use Creative Commons licenses. You’ll find many more case studies on the Creative Commons site.
