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. A straight line is shown and is marked with three angles. The first angle measures 80 degrees. The second angle measures 60 degrees. The third angle is labeled y. The line between the 60 degree angle and angle y extends below the straight line. The angle formed is labeled angle x. Write and solve an equation to determine the measure of angle x.

    well, we know the angles 60, 80, and y form a straight line, which means that their sum is 180 x and y are vertical angles, so they are equal

    SUM means add if 60, 80, and y have a sum of 180, what is the equation?

    60+80+y=180?

    great! but we're not done yet since we want an equation for x, we have one more step if x is the same as y, then we can replace y with x in the equation so what is the new equation?
