A) 1 rt. angle
B) 2 rt angle
C) \[270{}^\circ \]
D) \[300{}^\circ \]
Correct Answer: B
Solution :
Vertical Angle of the five pointed star ACEBDA \[=\frac{1}{3}\times \frac{(2\times 5-4)\times {{90}^{o}}}{5}={{36}^{o}}\] \[\therefore \] Sum of the 5 vertical angles of this star \[=5\times {{36}^{o}}\] \[={{180}^{o}}=2\,rt.\] anglesYou need to login to perform this action.
