The exterior angles of any polygon add up to 360° (imagine walking round any polygon - you will have made a complete turn).
There are six external angles in a hexagon. If it is a regular hexagon, each external angle will be 360°/6 = 60°.

Hexagon has 6 sides so 360/6 = 60 degrees interior angle therefore exterior angle = 360 - 60 = 300 degrees
Each interior angle of a decagon is 144 degrees.An exterior angle is 180 - measure of interior angle.There exterior angle of decagon is 180-144which is equal to-36
Each interior angle measures: 152o 18' 27.69''
if the interior angle is 150 the exterior angle equals 30. since exterior angle equals 360/ by number of sides the number of sides equals 360/30 which equal 12
Sum of exterior angles = 360 degrees. If each one is 15 degrees then there must be 360/15 = 24 of them.
