Answer:
A reflection of D over line l would simply look like a backwards D. Reflecting it again over the line m would make it look like it did originally, a normal D.
Step-by-step explanation:
Ok, find change then divide by years elapsed
change=310-280 million=30 million
number of years elapsed=10
30mil/10=3mil
3million per year was the population growth rate
Dodecagon is a plane figure with 12 sides. To find the sum of angles of a dodecagon, we have to use the formula of sum of angles of a polygon with n sides, which is
S= (n-2)180
For Dodecagon , n=12. Therefore on substituting 12 for n , we will get
S= (12-2)180 =10*180 = 1800 degree .
SO the sum of angle measures of a dodecagon is 1800 degree .
Yes! your right. The answer is correct :)
The answer would be 7 cups....... if it’s wrong I would recommend you to use Brainfuse
