What is the sum of the measures of interior angles ofna regular polygon if each exterior angle measures 72°?
WARRIOR [948]
We know that

The exterior angle measures of a polygon must add up to 360°, 

therefore

 360°/72°=5 exterior angles

so

5 exterior angles, would mean 5 interior angles and therefore  5 sides to the polygon

The exterior angle and the interior angle of any polygon are supplementary and must add up to 180°.

exterior angle+interior angle=180°

interior angle=180°-exterior angle

interior angle=180°−72°-------> 108°
Each interior angle is 108°

The sum of the interior angles would be 

5*108°=540°

the answer is

540°

What’s the answer???(SOMEONE PLEASE HELP ME)
sweet [91]

Answer:

Let's solve for f.

fx=

4x−3

x−10

Step 1: Multiply both sides by x-10.

fx2−10fx=4x−3

Step 2: Factor out variable f.

f(x2−10x)=4x−3

Step 3: Divide both sides by x^2-10x.

f(x2−10x)

x2−10x

=

4x−3

x2−10x

f=

4x−3

x2−10x

Answer:

f=

4x−3

x2−10x

Let's solve for g.

gx=

2x−8

x−10

Step 1: Multiply both sides by x-10.

gx2−10gx=2x−8

Step 2: Factor out variable g.

g(x2−10x)=2x−8

Step 3: Divide both sides by x^2-10x.

g(x2−10x)

x2−10x

=

2x−8

x2−10x

g=

2x−8

x2−10x

Answer:

g=

2x−8

x2−10x
