A) \[{{90}^{o}},\,\,{{180}^{o}}\]
B) \[{{36}^{o}},\,\,{{144}^{o}}\]
C) \[{{72}^{o}},\,\,{{108}^{o}}\]
D) \[{{52}^{o}},\,\,{{104}^{o}}\]
Correct Answer: C
Solution :
Let the adjacent angles of a parallelogram be \[2x\]and \[3x\]and sum of adjacent angles of parallelogram is \[{{180}^{o}}.\] \[\therefore \]\[2x+3x={{180}^{o}}\] \[\Rightarrow \]\[5x={{180}^{o}}\Rightarrow x={{36}^{o}}\] \[\therefore \]Angles are \[{{72}^{o}}\]and\[{{108}^{o}}.\]
