A) \[131{}^\circ \]
B) \[136{}^\circ \]
C) \[112{}^\circ \]
D) \[108{}^\circ \]
Correct Answer: A
Solution :
Let x and y be the largest and smallest angles of parallelogram. By hypothesis \[x=3y-16\] Also in a parallelogram, \[x+y={{180}^{o}}\] or \[(3y-16)+y={{180}^{o}}\] or \[4y=196\] \[\therefore \] \[y=49\] \[\therefore \] \[x=49\times 3-16\] \[=147-16={{131}^{o}}\]You need to login to perform this action.
