$\huge\mathfrak\pink{Answer ⤵}$

1.

Pentagon , 5 , 5-2=3 , (5-2)180=3×180=540 ,

$\frac{(5 - 2)180}{3} = \frac{540}{3} = 180$

2.

nonagon , 9, 9-2=7 , (9-2)180=7×180=1260 ,

$\frac{(9 - 2)180}{3} = \frac{1260}{3} = 420$

3.

hexagon , 6 , 6-2=4 , (6-2)180=720 ,

$\frac{(6 - 2)180}{3} = \frac{720}{3} = 240$
