One of the angles of a parallelogram is \[26{}^\circ \]. What is the difference between the adjacent angles of the parallelogram?

A)  \[138{}^\circ \]                       

B)  \[144{}^\circ \]

C)  \[172{}^\circ \]           

D)  None of these

Correct Answer: D

Solution :

\[\angle PQR=180{}^\circ -26{}^\circ =154{}^\circ \] \[\therefore \] Required difference\[=154{}^\circ -26{}^\circ =128{}^\circ \]
