A figure is a regular n-gon. Which of the following expressions represents the sum of the measures of
the exterior angles of the polygon, one at each
vertex?
A. (180 - 10°
360
B. 180
12
C. (n - 2)180°
D. 360°

The correct answer is D. 360°

Step-by-step explanation:

The sum of all the exterior angles of a regular n-gon or a polygon is always equal to 360°.

Let us consider the image attached.

First of all let us consider the triangle.

As per the property of exterior angles: The exterior angle is equal to the sum of 2 opposite interior angles.

Where are the interior angles of the triangle.

Adding the above equations:

The sum of interior angles of a triangle is always equal to 180°

Hence, proved that the sum of exterior angles is .

So, the correct answer is D.

answer: b)

step-by-step explanation:

its a dot plot because since the score is not high numbers.
