What is the smallest degree of rotation that will map a regular 20-gon onto itself?

Step-by-step explanation:

For a regular 20-gon, since  there are 20 vertices that the polygon can be rotated  and be mapped onto itself .Thus the order of symmetry of 20-gon is 2.

To find the degrees of rotational symmetry, we need to divide 360° by the order of symmetry.

Thus, the degree of rotation=

Hence,  the smallest degree of rotation that will map a regular 20-gon onto itself=

c - they will have the same distribution

step-by-step explanation:

this is the only one that could make sense. : )

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

hope this ! ~
