19. What is the sum of the measures of the exterior angles in a nonagon? Explain.

1 answer:

4 0

Answer: 360°.

Explanation.

The sum of the measures of the exterior angles of any simple polygon is 360°. That is true for triangles, rectangles, pentagons, hexagons, a so on, any polygon including, of course, the nonagon.

You can verify this if you draw the nonagon with its 9 exterior angles. You can realize that you may translate every angle to one common vertex and that the sum of all angles is equal to a complete turn around the vertex. Of course, you know that a complete turn is an agle of 360°.

Answer:

see the explanation

Step-by-step explanation:

A proportion is the ratio (quotient) between two numbers

Twelve hundredths to three is ----> $\frac{0.12}{3}$

Twenty-four hundredths to eight ----> $\frac{0.24}{8}$

therefore

Twelve hundredths is to three as twenty-four hundredths is to eight

$\frac{0.12}{3}=\frac{0.24}{8}$
