Question

Find the sum of the degree measures of the internal angles in the polygon shown below:

• A. ${600}^o$
• B. ${720}^o$
• C. ${900}^o$
• D. ${1080}^o$

Answer 1

The correct option is C ${900}^o$

The figure shown is a heptagon (polygon with 7 sides)
$\therefore$ Sum of th edegree measures of the internal angles of a heptagon.
$=(7-2)\times {180}^o=5\times {180}^o={900}^o$
