how to find coterminal angle
To find a positive and a negative angle coterminal with a given angle, you can add and subtract 360Â° if the angle is measured in degrees or 2Ï if the angle is measured in radians. Example 1: Find a positive and a negative angle coterminal with a 55Â° angle. 55Â° â 360Â° = â305Â°.55Â° + 360Â° = 415Â°.A â305Â° angle and a 415Â° angle are coterminal with a 55Â° angle. Example 2: Find a positive and a negative angle coterminal with a angle. A angle and a angle are coterminal with a angle.ind a positive and a negative angle coterminal with a 55Â° angle. 55Â° â 360Â° = â305Â°. 55Â° + 360Â° = 415Â°. A â305Â° angle and a 415Â° angle are coterminal with a 55Â° angle. Example 2: Find a positive and a negative angle coterminal with a angle. A angle and a angle are coterminal with a angle.
