A) \[5{}^\circ \]
B) \[10{}^\circ \]
C) \[15{}^\circ \]
D) \[20{}^\circ \]
Correct Answer: C
Solution :
(c): \[\angle EOD=\text{ }5m{}^\circ \] (by principle of vertically opposite \[\angle les\]) \[\therefore \text{ }5m+5m+5m+5m+2m+2m=360{}^\circ \] \[\Rightarrow \,\,\,24m=360{}^\circ \] \[\Rightarrow \,\,\,m=15{}^\circ \]
