Geometry math question no Guessing and Please show work thank you

Answer 1

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

$S = \frac{(n-2)180}{n}$

ANd S=135

So we will get

$135= \frac{(n-2)180}{n}$

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 .

Answer 2

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

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

B. 8 sides
