Answer:

(n-2)×180

where n is no. of sides

(10)180

1800°

so ans. is d. none

pleasee mark as brain list

Answer 2

$\small{ \underline{ \mathfrak{ \purple{formula \: to \: find \: angle}}}}$

(n-2)180

$\small{ \underline{ \mathfrak{ \purple{operations}}}}$

no. of sides = 12

according to formula:

(12-2)180

10 * 180

1800

answer = d. none
