A) \[90{}^\circ \]
B) \[80{}^\circ \]
C) \[30{}^\circ \]
D) \[60{}^\circ \]
Correct Answer: B
Solution :
Sum of interior angles of a hexagon are \[720{}^\circ \] \[\therefore \]\[x{}^\circ +(x-5){}^\circ +(x-5){}^\circ +(2x-5){}^\circ +(2x+20){}^\circ \]\[=720{}^\circ \] \[9x=720{}^\circ \] \[x=80{}^\circ \]You need to login to perform this action.
