Question

A road sign is in the shape of a heptagon (7 sides). What is the measure of each angle on the sign? Round to the nearest tenth. I gave y'all the exact question, I have no idea where to start.

Answer 1

`((n-2)\cdot180)/(n)\\\\ n=7\\ ((7-2)\cdot180)/(7)=(5\cdot180)/(7)\approx 128.6^(\circ)`
