Question

find the sum of the angle measures of each polygon 205 - gon

Answer 1

To calculate the sum of the angle measures of a polygon with n sides we use the formula:

$(n-2)\cdot180$

for a 205-gon

$\begin{gathered} (205-2)\cdot180 \\ 203\cdot180 \\ 36540 \end{gathered}$

The sum of the angles of a 205-gon is 36540°
