Find an angle between 0 degree and 360 degree that is coterminal with given angle.
a. 361 degree
b. -100 degree
c. 1270 degree
To find the coterminal angle, you can subtract or add 360° until the angle is between 0 and 360°.
For example, 361° is more than 360° so we subtract 360° to get 1°. Since 1° is between 0 and 360°, it is the coterminal angle with 361°.
You can apply the same method for the other two questoins.
