51.43^{\circ} is the measure of each exterior angle in a regular heptagon.


Explanation:

In a regular polygon,

\text{the size of each exterior angle}\ \ =\ \ 360^{\circ} \div\ \text{number of sides}

In this case, the size of the exterior angle of a regular heptagon is 51.43^{\circ} because 360^{\circ} \div 7 = 51.43^{\circ}

And the interior angle must be 128.57^{\circ} because 180^{\circ} – 51.43^{\circ} = 128.57^{\circ}
