C) \[9\]
D) \[10\]
Correct Answer: B
Solution :
Let the polygon have 'n' sides. Sum of the interior angles \[=(n-2)\times {{180}^{o}}\] \[\therefore \] \[n\times {{150}^{o}}=(n-2)\times {{180}^{o}}\] \[\Rightarrow \] \[150n=180n-{{360}^{o}}\] \[\Rightarrow \] \[n\,=12\]You need to login to perform this action.
