Question

Углы правильного восемнадцатиугольника равны ... 160° 125° 164° 150°

Answer 1

Сумма углов N-угольника считается по формуле (N-2)*180°

Значит сумма углов равна 16*180=2880°, один угол равен 160°

Answer 2

180°(n-2)=180°(18-2)=180°*16=2 880

2 880:18=160°

Answer 3

To find the interior angles of a regular polygon (in this case, an octadecagon or an 18-sided polygon), we can use the formula:

Interior Angle = (180 * (n - 2)) / n

Where "n" is the number of sides (in this case, n = 18).

So, the interior angle of the regular octadecagon is:

Interior Angle = (180 * (18 - 2)) / 18 Interior Angle = (180 * 16) / 18 Interior Angle = 2880 / 18 Interior Angle = 160 degrees

Since all the interior angles of a regular polygon are congruent, each angle in the regular octadecagon measures 160 degrees. The angles you provided (160°, 125°, 164°, 150°) seem to be measurements of specific angles in an octadecagon but not all of them.
