A) \[{{72}^{o}},{{108}^{o}},{{72}^{o}},{{108}^{o}}\]
B) \[{{72}^{o}},{{108}^{o}},{{70}^{o}},{{110}^{o}}\]
C) \[{{80}^{o}},{{100}^{o}},{{80}^{o}},{{100}^{o}}\]
D) None of these
Correct Answer: A
Solution :
\[2x+3x={{180}^{o}}\] \[5x={{180}^{o}}\] \[x={{36}^{o}}\] Hence, angles are \[{{72}^{o}}\] and \[{{108}^{o}}\] respectively. As opposite angle of parallelogram are equal. Therefore, measure of all angles are \[{{72}^{o}}\], \[{{108}^{o}}\],\[{{72}^{o}}\], \[{{108}^{o}}\].
