A) \[{{32}^{o}}\]
B) \[{{30}^{o}}\]
C) \[{{27}^{o}}\]
D) \[{{20}^{o}}\]
Correct Answer: D
Solution :
[d] Sum of external angles of a polygon = 360° We have, \[k+3k+6k+7k+10k=\left( 2\times 5-4 \right)\times 90{}^\circ \] \[\Rightarrow \,k=20{}^\circ \] \[\therefore \] Smallest angle = 20°You need to login to perform this action.
