Answer:

<h3><u>Required Answer</u><u> </u><u>:</u><u>-</u></h3>

Let the number of sides=x

  • Each angle measures 9°

As we know that in a polygon

{\boxed{\sf Sum\;of\:exterior\:angles=360°}}

  • Substitute the values

{:}\longrightarrow\sf 9x=360

{:}\longrightarrow\sf x={\dfrac {360}{9}}

{:}\longrightarrow\sf x=40

\thereforeNumber of sides=40.

Answer:

40

Step-by-step explanation:

The sum of the exterior angles of a polygon = 360°

Divide this by the value of 1 exterior angle to find the number of sides n

n = 360 ÷ 9 = 40

Rounded to the nearest hundredth, what is the positive solution to the quadratic equation 0 = 2x2 + 3x – 8?
zmey [24]
2x² + 3x -8 = 0

a = 2 , b = 3 , c = -8
So..
D = b²-4ac = 9 + 64 = 73

for bigger solution , use x = -b + √D / 2a
For smaller solution, use x = -b - √D / 2a

So
= -3 + √73 / 2. 2
= 1/4 (√73 -3)

Hopefully helpfull.. ^_^
