Find an angle coterminal to $\displaystyle \alpha$, between $\displaystyle {0}^{\circ}$ and $\displaystyle {360}^{\circ}$, by subtracting multiples of $\displaystyle {360}^{\circ}$.

(a)  $\displaystyle \alpha={3000}^{\circ}$ 

 $\displaystyle \beta={3000}^{\circ}-{360}^{\circ}{(}$$\displaystyle {)}=$

(b)  $\displaystyle \alpha=-{4388}^{\circ}$ 

 $\displaystyle \beta=-{4388}^{\circ}-{360}^{\circ}{(}$$\displaystyle {)}=$
