The angle of a regular N-gon is 135 degrees. Find N.
August 6, 2021 | education
| In the initial data for this task, it is reported that the magnitude of each of the angles of this regular N-gon is 135 °, therefore, the sum of all the angles of this polygon should be equal to 135 * N degrees.
On the other hand, the sum of the angles of any regular N-gon can be calculated using the formula 180 * (N – 2), therefore, we can compose the following equation:
180 * (N – 2) = 135 * N,
solving which, we get:
180N – 360 = 135N;
180N – 135N = 360;
45N = 360;
N = 360/45 = 8.
Answer: N = 8.
