Answer:

18 sides

Step-by-step explanation:

with regular polygons it is best to remember that:

(1) all the EXTERIOR angles add up to 3600

(2) 1 exterior angle+1 interior angle =1800

Work with the exterior angles. In this case:

1 int. <=180−160=200

No. of sides =36020=18

What's the product of 3 2⁄3 and 14 2⁄5 ?

kodGreya [7K]

Here is your answer:

3 2/3 = 11/3

14 2/5 = 72/5

11 × 72 = 792

3 × 5 = 15

792/15 divided into $52\frac{12}{15}$

12 ÷ 3 = 4

15 ÷ 3 = 5

"= 52 4/5 into a improper fraction is 264/5"

Hope this helps!

1)

x + 2y = 21

+ -x + 3y = 29

--------------------------

5y = 50

y = 10

x + 2(10) =21

x = 1

2)

6x + 6y = 30

+ 15x - 6y = 12

-------------------------------

21x = 42

x = 2

6(2) + 6y = 30

6y = 18

y = 3
