What is the measure of each interior angle of a regular heptagon? Round to the nearest tenth.
a.
96.2°
c.
112.2°
b.
98.6°
d.
128.6°

Answer 1

The equation for the sum of the angles in a polygon of n sides is:
\[180(n-2)\]Since it is a 7 sided figure, we plug in n=7:
\[180(7-2)=180 \times 5 = 900 degrees\]Since the sum of the seven angles is 900, each angle will be:
\[\frac{ 900 }{ 7 } degrees\]
