Answer:
Step-by-step explanation:
Always , sum of exterior angle of any polygon = 360
sum of exterior angle of 11- sided polygon = 360
Measurement of an exterior angle of 11-sided polygon = 360/11
= 32.73
Measurement of an interior angle of 11-sided polygon = 180 - 32 8/11
= 180 - 32.73= 147.27
1/6 because 2•1=2 and 3•4=12 and 2/12=1/6
