What is the name of the regular polygon that measures 140゚
andrezito [222]

Answer:

The regular polygon is a nonagon

Step-by-step explanation:

<u><em>The correct question is</em></u>

What is the name of the regular polygon that each interior angle measures 140゚?

we know that

The formula to find the sum of the interior angles in a regular polygon is equal to

n(a)=(n-2)180\°

where

n is the number of sides of the regular polygon

a is the measure of each interior angle of the regular polygon

we have

a=140\°

substitute in the formula and solve for n

n(140\°)=(n-2)180\°

140n=180n-360

180n-140n=360

40n=360

n=9\ sides

so

The regular polygon has 9 sides

therefore

The regular polygon is a nonagon

Solve and check:8a-4=25+6(a-8)
OlgaM077 [116]
8a - 4 = 25 + 6 (a - 8)

(distribute the 6)

8a - 4 = 25 + 6a - 48

(combine like terms 25 - 48)

8a - 4 = 6a - 23

( subtract 6a from both sides)

2a - 4 = -23

(add 4 to both sides)

2a = -19

(divide both sides by 2)

a = - 9.5

////CHECK/////

8 (-9.5) - 4 = 25 + 6 ( -9.5 -8)

(plug each side into a calculator)

-80 = -80

FINAL ANSWER:

a = -9.5
