55% of 20 is 11. the answer is 20
Answer:
1. 17 - gon
sum of the of measures of interior angles = 180(n-2).....(formula)
here n = 17
therefore, 180(17-2)
= 180(15)
= 2700 degrees
2] 24 - gon
sum of the of measures of interior angles = 180(n-2).....(formula)
here n = 24
therefore, 180(24-2)
= 180(22)
= 3960 degrees.
