Explanation:
The mean angle is all the angles added up together then divided by how many angles they were. For example:
I have four angles 44°, 37°, 29° and 67°, what I would do is add them all up together, i.e, 44+37+29+67, which equals to 180. Then I would divide 180 by how many angles they were, so I would do 180÷4 which equals to 45. So the mean angle would be 45°, that's how you find the mean, hope that helps.
X has an elevation of 1600m
Y has an elevation of 1240m
Difference between the two elevations: 1600-1240=360m
B.rely on wind power rather than electricity
1000 miles per hour
To make one complete rotation in 24 hours, a point near the equator of the Earth must move at close to 1000 miles per hour (1600 km/hr). The speed gets less as you move north, but it's still a good clip throughout the United States. Hope this helps!
