    B)  \[{{3}^{{}^\circ }},{{4}^{{}^\circ }}\]        

    C)  \[{{2}^{{}^\circ }},{{1}^{{}^\circ }}\]                   

    D)  None of these

    Correct Answer: A

    Solution :

    (a): By property of transversal on \[\parallel \] lines, \[12x={{60}^{{}^\circ }}\Rightarrow x={{5}^{{}^\circ }}\] \[7y={{28}^{{}^\circ }}\Rightarrow y={{4}^{{}^\circ }}.\]
