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.
