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

Let n (AUB)=32n(B)=16and n(ANB)9 find n (A)​
Lubov Fominskaja [6]

Answer:

32

Step-by-step explanation:

n(A∪B)=n(A)+n(B)−n(A∩B)−−−−−−−(1)

Given n(A)= ? we represent with x

n(B)= 16

n(A∪B) = 32

Substituting in equation 1 to get n(A)

32  = n(A) + 9 − 9

⇒n(A) = 32 − 0

n(A)  = 32

to confirm this we put the values into the formula below

n(A∪B)=n(A)+n(B)−n(A∩B)−−−−−−−(1)

32 =  32 + 9 - 9

A line that is perpendicular to y=-2/7x+9y and that passes through the point (4, -6)
IrinaK [193]
--------------------------------------------------
Find Slope :
--------------------------------------------------
y = -2/7x + 9
Slope = -2/7
Perpendicular slope= 7/2

--------------------------------------------------
Find y - intercept :
--------------------------------------------------
y = mx + b
y = 7/2 x + b
At (4, -6)
-6 = 7/2 (4) + b
-6 = 14 + b
b = -6 - 14
b = -20

--------------------------------------------------
Form equation :
--------------------------------------------------
y = mx + b
y = 7/2 x - 20
2y = 7x - 40

--------------------------------------------------
Answer: 2y = 7x - 40
--------------------------------------------------
