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
keeping in mind that there 60 seconds in 1 minute, and about 1.609 kilometers in 1 mile.

18 - 25 = -7
11 - 18 = -7
4 - 11 = -7
The common difference is -7.
Congruent. cause they have the same angles
