Respuesta :

(12 - 2) * 180 = 1,800/12 = 150

(8 - 2) * 180 = 1,080/8 = 135

B. 8 sides

Riia

Here we have to use the following formula to find the number of sides,n

[tex] S = \frac{(n-2)180}{n} [/tex]

ANd S=135

So we will get

[tex] 135= \frac{(n-2)180}{n} [/tex]

135n = 180n -360

Subtracting 180n to both sides

-45n =-360

Dividing both sides by -45

n = 8 .

So the number of sides =8. And the correct option is B .
