We can do it with the equation written; we'll try that next. I find it easier to remember the exterior angles, which are the supplements of the interior angles, add to 360 degrees.

The exterior angle is 180 - 144 = 36 degrees. n = 360/36 = 10

10 sides

Let's try it your way now.

$\dfrac{180(n-2)}{n} = 144$

180n-360 = 144 n

36n = 360

$n = 10 \qquad\checkmark$
