Find a positive angle less than 360° or 2π that is coterminal with the given angle.
-$$- \frac { 2 \pi } { 9 }$$
A) $\frac { 16 \pi } { 9 }$
B) $\frac { 34 \pi } { 9 }$
C) $\frac { 25 \pi } { 9 }$
D) $\frac { 2 \pi } { 9 }$

To find a positive angle coterminal with $-\frac{2\pi}{9}$, you can add $2\pi$ to the given angle since $2\pi$ is a full rotation in radians. $-\frac{2\pi}{9} + 2\pi = -\frac{2\pi}{9} + \frac{18\pi}{9} = \frac{16\pi}{9}$.
