    In adjoining the figure the value of x is:                                                               

    A)  \[\angle 1+\angle 2+\angle 3+\angle 4=\angle 5+\angle 6+\angle 7+\angle 8\]                             

    B)  \[\angle 1+\angle 2+\angle 3+\angle 4<\angle 5+\angle 6+\angle 7+\angle 8\]

    C)  \[\angle 1+\angle 2+\angle 3+\angle 4>\angle 5+\angle 6+\angle 7+\angle 8\]        

    D)  \[AB=2x+5,\]

    Correct Answer: C

    Solution :

    Since, exterior angle of A is equal to sum of opposite interior angles. \[\angle CBP\]  \[{{105}^{o}}\] \[{{115}^{o}}\] \[{{135}^{o}}\]
