In the figure, angle A = 28 degrees, angle B = 74 degrees and angle C = 26 degrees. If x and  y are the measures of the angles in which they are shown, what is the value of x+y?

If x and  y are the measures of the angles in which they are shown, what is the value of x+y?

\(\begin{array}{|rcll|} \hline x-A-B+y &=& C \\ x+y &=& A+B+C \\ x+y &=& 28^{\circ} + 74^{\circ} + 26^{\circ} \\ \mathbf{x+y} & \mathbf{=} & \mathbf{128^{\circ}} \\ \hline \end{array}\)
