Given: an n-gon Prove: The sum of the measures of the interior angles is 180(n – 2)°. Complete the missing parts of the paragrap
icang [17]

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 <u>n-3</u> diagonals.

2. These diagonals form <u>n-2</u> triangles.

3. The sum of the interior angle measures of a triangle is <u>180</u> degrees.

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

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

Three different golfers played a different number of holes today. Rory played 9 holes and had a total of 42 strokes. Alicia play
choli [55]

Answer:

Alicia is the golfer who has had the lowest number of strokes per hole

Step-by-step explanation:

we know that

The unit rate of the number of strokes per hole is equal to divide the number of strokes by the number of holes

Let

x ----> the number of strokes

y ----> the number of holes

we have

<em>Roy</em>

x=42\ strokes\\y=9\ holes

\frac{x}{y}=\frac{42}{9}=4.67\ strokes\ per\ hole

<em>Alicia</em>

x=79\ strokes\\y=18\ holes

\frac{x}{y}=\frac{79}{18}=4.39\ strokes\ per\ hole

<em>Rickie</em>

x=123\ strokes\\y=27\ holes

\frac{x}{y}=\frac{123}{27}=4.56\ strokes\ per\ hole

Compare

4.39 < 4.56 < 4.67

therefore

Alicia is the golfer who has had the lowest number of strokes per hole
