I believe the length of the fence is 640. (Don't count on my answer, it may not be right).
Answer:
Step-by-step explanation:
Sum of all the angles of 12 sided polygon= (n -2)*180
= (12 - 2 )*180 = 10 * 180 = 1800
Four interior angle each of xº + 8 interior angles each of 2xº = 1800
4*x + 8*2x = 1800
4x + 16x = 1800
20x = 1800
x = 1800/20
x = 90°
I tired I don’t know if it’s correct
The conclusion that is justified based on the research is that he rejected the null hypothesis that women drank the same amount of water per kg of body weight per day as men.
