If the sum of all interior angles of a regular polygon is 1080 degrees then number of sides of the polygon is?

MakcuM [25]

Answer: 8

Step-by-step explanation:

The formula for the sum of the angles of a polynomial is:

$S_n=180(n-2)$

1080 = 180(n - 2)

1080 = 180n - 360

1440 = 180n

8 = n

Answer :-

9(3+√3) feet

Step by step explanation :-

A triangle is given to us. In which one angle is 30° and length of one side is 18ft ( hypontenuse) .So here we can use trignometric Ratios to find values of rest sides. Let's lable the figure as ∆ABC .

Now here the other angle will be = (90°-30°)=60° .

In ∆ABC ,

=> sin 30 ° = AB / AC

=> 1/2 = AB / 18ft

=> AB = 18ft/2

=> AB = 9ft .

Again In ∆ ABC ,

=> cos 30° = BC / AC

=> √3/2 = BC / 18ft

=> BC = 18 * √3/2 ft

=> BC = 9√3 ft .

Hence the perimeter will be equal to the sum of all sides = ( 18 + 9 + 9√3 ) ft = 27 + 9√3 ft = 9(3+√3) ft .

<h3>Hence the perimeter of the triangular pathway shown is 9 ( 3 + √3 ) ft .</h3>

I need help with the equation I know what the value of x is . Also their is only one equation .

Sindrei [870]

40+90=130
180-130=50
50+130=180
x=130
