The sum of the measure of the interior angles of a polygon is 1980°. What polygon is it? 10-gon 11-gon 12-gon 13-gon

tiny-mole [99]

Answer:

13-gon

Step-by-step explanation:

The sum of the interior angles of a polygon with n sides is:

S = 180° (n − 2)

If S = 1980°, then:

1980° = 180° (n − 2)

11 = n − 2

n = 13

A new neighborhood activity complex is being built in erie. The perimeter of the rectangular playing field is 256 yards. The len

maw [93]

Answer:

The length of the rectangular playing field is 84 yards and the width is 44 yards

Step-by-step explanation:

Let

x ------> the length of the rectangular playing field

y -----> the width of the rectangular playing field

we know that

The perimeter of the rectangular playing field is equal to

$P=2(x+y)$

$P=256\ yd$

$256=2(x+y)$ ------> equation A

we have that

$x=2y-4$ -----> equation B

Solve the system by substitution

Substitute equation B in equation A and solve for y

$256=2(2y-4+y)$

$128=3y-4$

$3y=128+4$

$3y=132$

$y=44$

Find the value of x

$x=2(44)-4=84$

therefore

The length of the rectangular playing field is 84 yards and the width is 44 yards

Can someone help me find the answer to the following?

Ludmilka [50]

To solve this, we'll use Euler's Polyhedral formula.

This formula states that in any polyhedron, the number of vertices V, faces F, and edges E, satisfy:

$V+F-E=2$

If we solve for the edges E, we'll get:

$V+F-2=E$

Using the data given,

$\begin{gathered} V+F-2=E \\ \rightarrow6+8-2=E \\ \rightarrow12=E \end{gathered}$

We get that the polyhedron would have 12 edges
