Since `piradians =180degrees`

2`piradians = 360 degrees`

When you add (+) or subtract (-) 360 degrees or 2`piradians`

to a solution you will end at the same measurement as you started with;

therefore the correct solution is both a: adding 360 and b: subtracting 360

**which makes choice "d" both of the above solutions are correct**
