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

# #
# #

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}#
