A) 4
B) 8
C) 12
D) 16
Correct Answer: C
Solution :
Each interior angle \[=\frac{(n-2)\times 180{}^\circ }{n}\] \[\therefore \] \[=\frac{(n-2)\times 180{}^\circ }{n}=150{}^\circ \] \[(n-2)\times 180{}^\circ =n\times 150{}^\circ \] \[30n=360{}^\circ \] \[n=\frac{360{}^\circ }{30}\] \[n=12\]You need to login to perform this action.
