Given: an n-gon

Prove: The sum of the measures of the interior angles is 180(n – 2)°.

Complete the missing parts of the paragraph proof.

We are given an n-gon, which has n sides and n vertices.

Answers:

1. If we choose one of the vertices, we can draw n-3 diagonals.

2. These diagonals form n-2 triangles.

3. The sum of the interior angle measures of a triangle is 180 degrees.

4. n – 2 triangles would have an interior angle measure sum of 180 degrees.

5. Therefore, the sum of the measures of the interior angles of an n-gon is 180(n – 2)°.

choice b is correct

step-by-step explanation:

we have been given the following system of inequalities;

we are required to graph the solution to the system of inequalities. using a graphing tool, the graph of the system is as shown in the attachment. the continuous line represents the graph of while the dotted line represents .

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50
