Explanation:
If two or more angles have the same terminal side when in standard position, then they are coterminal.
To find a positive angle that is coterminal with
, we add
, that is one complete positive revolution t get:
![310\degree+360\degree=670\degree](https://img.qammunity.org/2020/formulas/mathematics/middle-school/l6nitdi2jjhdawl8vv8dicrs60t17a5j95.png)
To find a negative angle that is coterminal with
, we subtract
, that is one complete negative revolution t get:
![310\degree-360\degree=-50\degree](https://img.qammunity.org/2020/formulas/mathematics/middle-school/6lmd2e3sg25sw6ygj56b8jm488ydv2vlju.png)
