two angles are coterminal when the angles themselves are different, but their sides and vertices are identical
you can remember the definition of the coterminal angle as angles that differ by a whole number of complete circles

given
complete circle is


....positive value, we can stop now

since we need greatest value, choices are and ,
since , our solution is
