Sum of the Measures of the Exterior Angles of a Polygon

$K°$ is the maximum exterior angle possible for a regular polygon, then find the value of $k$.

Examine the table. (Each figure is divided into triangles and the sum of the angles deduced from that.)

Figure
Side	$3$	$4$	$5$	$6$
Angle	$180°$	$2\times 180°$ $=(4-2)\times 180°$	$3\times 180°$ $=(5-2)\times 180°$	$4\times 180°$ $=(6-2)\times 180°$
