Select the correct answer. Given: Three lines are drawn from the same point of origin from angles 1 and 2 as shown Given the measure of the angle, MXY is equal to the measure of the angle KXY and the vertical measure of the JXM minus the measure of the NXK both point toward the angle of addition in the measure of the JXY equal to the measure of the NXY What is the conclusion reached by this proof?
