    Direction: Observe the given figure in which \[l||m\]and n is the transversal and answer the questions that follow.
    If the measure of 'c' is \[{{110}^{o}}\] what is the measure of 's'?

    A)  \[{{45}^{o}}\]                   

    B)         \[{{110}^{o}}\]

    C)  \[{{70}^{o}}\]     

    D)         \[{{180}^{o}}\]

    Correct Answer: C

    Solution :

                   c and s are interior angles on the same side of transversal, which are supplementary. So, if \[c={{110}^{o}},\] 's' measures \[{{180}^{o}}-{{110}^{o}}={{70}^{o}}.\]
