Answer:
59°
Step-by-step explanation:
From the diagram, shown in the attachment line x and y are parallel lines.
Angle 7 and angle 6 are angles on a straight line.
The two angles will add up to 180 degrees.
[tex]\angle 7+\angle 6=180[/tex]
But angle 7 measures 121°.
This implies that:
[tex]121+\angle 6=180[/tex]
Solve for angle 6 to get;
[tex]\angle 6=180-121[/tex]\
[tex]\angle 6=59\degree[/tex]
