What part of the extended angle is the angle: 30 degrees, 60 degrees

What part of the extended angle is the angle: 30 degrees, 60 degrees, 90 degrees, 120 degrees, 150 degrees, 15 degrees, 18 degrees, 36 degrees, 20 degrees.

The unfolded angle is 180 degrees.

Let’s find what part will be the value of the given angle from 180.

To express a part in fractions of a whole, you need to divide the part into a whole.

30 ° = 1/6 of the unfolded angle;

30/180 = 1/6;

60 ° = 1/3 of the unfolded angle;

60/180 = 1/3;

90 ° = 1/2 unfolded angle;

90/180 = 1/2;

120 ° = 2/3 of the unfolded angle;

120/180 = 2/3;

150 ° = 5/6 unfolded angle;

150/180 = 5/6;

15 ° = 1/12 of the unfolded angle;

15/180 = 1/12;

18 ° = 1/10 unfolded angle;

18/180 = 1/10;

36 ° = 1/5 of the unfolded angle;

36/180 = 1/5;

20 ° = 1/9 of the unfolded angle;

20/180 = 1/9;
