What is the smallest degree of rotation that will map a regular 18-gon onto itself?

2 answers:

6 0

Because the 18-gon is symmetrical, you can rotate it by 360/18 or 20 degrees. This is because when you rotate it by 20 degrees(to the left for explanation matters), any angle will now be in the position of its angle to its left.

Answer:

The answer is 20

Step-by-step explanation:

360 will be divided by 18 which will give you 20. For those of you who had the same question but instead of "18-gon" you had "20-gon" if you divide 360 by 20 your answer will be 18.

Solve for x.<br> 4x - 36<br> 3x + 10

Anestetic [448]

Answer:

x = 46

Step-by-step explanation:

Since the angles are equal to each other, make the equations equal to each other.

4x - 36 = 3x + 10 and simplify

x - 36 = 10

x = 46
