Question

What is the measure of angle 6, if lines x and y are parallel, and angle 7 measures 121°? 121° 69° 59° 49°

Answer 1

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.

$\angle 7+\angle 6=180$

But angle 7 measures 121°.

This implies that:

$121+\angle 6=180$

Solve for angle 6 to get;

$\angle 6=180-121$\

$\angle 6=59\degree$
