PLEASE HELP ASAP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!


In the figure below, 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.

80 + 60 + y = 180 and if y and x are vertical angles y = x

Adding angle x, the 80 degree angle, and the 60 degree angle should give you 180 degrees, a straight line, because they all lie on the straight line. So we can create the equation:

[tex]\sf x+80+60=180[/tex]

Simplify:

[tex]\sf x+140=180[/tex]

Subtract 140 to both sides:

[tex]\sf x=\boxed{\sf 40\textdegree}[/tex]
