5) Draw the angle in standard position: α \ = \ -\frac{38π}{9}
\color{red}{-\frac{38π}{9} \ \times \ \frac{180}{π} \ = \ -760°}
\color{red}{-760° \ + \ 360° \ = \ -400°}
\color{red}{-400° \ + \ 360° \ = \ -40°}
\color{red}{-40° \ + \ 360° \ = \ 320°}

6) Draw the angle in standard position: α \ = \ -\frac{55π}{18}
\color{red}{-\frac{55π}{18} \ \times \ \frac{180}{π} \ = \ -550°}
\color{red}{-550° \ + \ 360° \ = \ -190°}
\color{red}{-190° \ + \ 360° \ = \ 170°}

7) Draw the angle in standard position: α \ = \ -\frac{23π}{9}
\color{red}{-\frac{23π}{9} \ \times \ \frac{180}{π} \ = \ -460°}
\color{red}{-460° \ + \ 360° \ = \ -100°}
\color{red}{-100° \ + \ 360° \ = \ 260°}

8) Draw the angle in standard position: α \ = \ - 440°
\color{red}{-440° \ + \ 360° \ = \ -80°}
\color{red}{-80° \ + \ 360° \ = \ 280°}

9) Draw the angle in standard position: α \ = \ - 390°
\color{red}{-390° \ + \ 360° \ = \ -30°}
\color{red}{-30° \ + \ 360° \ = \ 330°}
