Find the area of the regular polygon.

Mathematics
1 answer:
Neporo4naja [7]4 years ago
8 0

Answer:

Then, the area is 222,48 in

Step-by-step explanation:

The area of the regular polygon is: 1/2 x perimeter x apothem.

The perimeter 6 times the number of sides of the polygon which is 9*6in = 54 in.

The apothem is: s/2tan(180/n)  where "s" is the lenght of the side and "n" the number of sides.

apothem = s/2tan(180/n) = 6in/(2tan(180/9)) = 8.24 in

Then, the area is:  1/2 x 54 in x 8.24 in = 222,48 in

E= \frac{17}{20}

E= 0.85

Therefore, 0.85 Euros have the same amount as 1 U.S dollar.

vlabodo [156]

Answer:

x²+2x+3....

Step-by-step explanation:

The given expression is:

5x3+10x2+15x/5x

To simplify this expression take out the common of the numerator:

5x is common in all three terms of the numerator:

Like,

5x(x²+2x+3)/5x

Now the value of the common and the denominator is same. Therefore 5x will be cancel out by 5x

Then the remaining term is:

= x²+2x+3

Thus the answer is  x²+2x+3....
