Question

do q. no. 2 with explanation​

Answer 1

Answer: n=13

Step-by-step explanation:

Please see the attached explanation

Answer 2

each exterior angle=360

between two exterior angle=(n-1)(n+2)

A.T.Q

the required difference=(360/n-1)-(360/n+2)

360(n+2)-360(n-1)/(n-1)*(n+2)

360n+720-360n+360/n-1*n+2

720+360/ n²+2n-n-2=6

1080/n²+n-2=6

1080=6n²+6n-12

6n²+6n-12=1080

6(n²+n-2=180)

n²+n-182=0

n²+14n-13n-182=0

n(n+14)-13(n+14)

(n-13) (n+14)=0

n=13,n=-1

n=13
