In the figure below, angle y and angle x form vertical angles. Angle y forms a straight line with the 80° angle and the 60° angle.


Write and solve an equation to determine the measure of angle x.

I am not sure about the equation...
but...vertical angles are congruent...so < x = < y

< y forms a straight line with 80 and 60.....a straight line measures 180 degrees.....so y = 180 - (80 + 60) = 180 - 140 = 40

therefore, the measure of < x is 40
