$140^{\circ}$ $color(green)(140^@$

Radians to degrees

$d^{\circ} = \frac{r^{c} \cdot 360}{2 π}$ $d^@ =( r^c * 360) / (2pi)$

Given $r = {(\frac{7 π}{9})}^{c}$ $r = ((7pi)/9)^c$

$d = ((7 cancel(color(blue)(pi))) * cancel(360)^color(red)(20)) / (cancel(9 * 2 )cancel (color(blue)(pi))$

$=> 7 * 20 = color(green)(140^@$
