Answer:

The mean would be 82

Step-by-step explanation:

To find the mean you add up all the numbers.

68 + 73 + 95 + 81 + 85 + 90 + 77 + 84 + 75 + 92 = 820

Then you divide that be the amount of numbers are given to you.

820 \div 10 = 82

And that is how you find the mean.

Sorry if it is wrong I'm tired.

How do you find the exterior angle of a polygon?
trasher [3.6K]

The sum of the measures of the interior angles of a polygon with n sides is (n – 2)180.

The measure of each interior angle of an equiangular n-gon is.

If you count one exterior angle at each vertex, the sum of the measures of the exterior angles of a polygon is always 360°.

Help pls asap!!!!! !!!!!
stiv31 [10]

Answer:

It is 40 degrees.

Step-by-step explanation:

You can start off by understanding this is not a right angle (exactly 90 degrees, think of a corner of a room) or and obtuse angle (more than 90 degrees, bigger than a right angle). With that information we know that it is an acute angle (less than 90 degrees, smaller than a right angle). With that we have 40 and 50 degrees left. When you compare the angle with the 40 degrees one, it is the same size. The angle 1 is a reflection of the triangle with the 40 degrees angle. Hope this helps :)
