SOLUTION :
Use formula of sum of interior angles of polygon:
- Sum = (n - 2) × 180°
- with n = number of side of the polygon.
if sum = 900° , Solve for n,
- 900° = (n - 2) × 180°
- n - 2 = 900°/180°
- n = 5 + 7
- n = 7
Hence , measure of each interior angles (in nearest hundredths) is:
- Sum/n = 900°/7
- n = [tex]{\boxed{\green{\sf{128.57 }}}}[/tex]
ANSWER :
- Therefore , measure of each interior angles (in nearest hundredths) is 128.57.
