What is the sum of the measures of the exterior angles of a nonagon?
olchik [2.2K]

For this case we have by definition, that the sum of the exterior angles of a polygon is equal to 360 degrees, only when considering only one exterior angle for each vertex of the polygon, regardless of the number of sides it possesses. That said we have to:

The external angle of a regular polygon is given by:

\frac {360} {n}

Where:

n: It is the number of sides of the polygon

Then, for a nonagon each exterior angle will measure:

\frac {360} {9} = 40 degrees

Answer:

40 degrees each exterior angle

360 degrees the sum

What is an equation of a line that passes through the point (-3 -7) and it’s parallel to the line 2x-3y=24
andrew-mc [135]

Answer:

y=(-2/3)x-9

Step-by-step explanation:

1) first put the equation in terms of y. You should get y=-(2/3)x-8.

2) parallel lines have the same slope so the slope for this line and the answer should be the same

3) using the form y=mx+b plug (-2/3) in as the slope or m

4) plug the point in to get your b value. you should have -7 =((-2/3)•(-3))+b

5) isolate the variable b and plug in your answer to the equation.
